[meta-python,1/9] python3-alembic: Upgrade 1.20.0 -> 1.20.1

Upgrade to release 1.20.1:

bug:

- [bug] [autogenerate] Fixed issue where a table or column comment
  set to an empty string would cause autogenerate to detect a
  comment change on every run.  As most backends, including
  PostgreSQL, MySQL, MariaDB and Oracle, don't store an empty
  string comment distinctly from no comment, autogenerate now
  treats an empty string comment the same as None when comparing
  comments. Additionally, an empty string comment is now rendered
  in op.create_table() and op.add_column() directives, where it was
  previously omitted.  Pull request courtesy vineoy.

- [bug] [autogenerate] [postgresql] Fixed rendering of the
  PostgreSQL ~sqlalchemy.dialects.postgresql.DOMAIN type in
  autogenerated migration scripts.  Previously the type was
  rendered using repr(), which omitted the check, not_null,
  default, collation, constraint_name, schema and create_type
  arguments and did not apply a dialect prefix to the underlying
  data type.  The full set of arguments is now rendered and the
  underlying data type is rendered using the standard
  type-rendering logic.  Pull request courtesy Sebastian Cao.

- [bug] [autogenerate] [postgresql] Fixed false-positive "Computed
  default cannot be modified" warning emitted during autogenerate
  when comparing PostgreSQL Computed columns whose reflected SQL
  expression includes type cast specifiers such as ::regconfig or
  ::text, which PostgreSQL adds to the expression as stored.  These
  cast specifiers are now stripped before comparison so that
  otherwise equivalent expressions no longer trigger the warning.
  Pull request courtesy Sebastian Cao.

- [bug] [autogenerate] [postgresql] Fixed issue where autogenerate
  would detect an unchanged PostgreSQL expression-based index as
  modified when the expression included type casts, such as a cast
  to a type with a length or precision, a nested cast, or a cast
  followed by a DESC modifier.

- [bug] [postgresql] Fixed bug where Operations.alter_column()
  against a PostgreSQL identity column would render an incomplete,
  invalid ALTER TABLE ... ALTER COLUMN statement with no clause at
  all when existing_server_default was omitted, even if there were
  no existing server default.  Pull request courtesy Riti Grover.

- [bug] [environment] Fixed issue where a third party plugin
  published using the alembic.plugins entrypoint, configured to
  refer to a plugin module as documented at
  alembic.plugins.toplevel, would cause import alembic to fail with
  a TypeError, as the loaded module was erroneously iterated rather
  than being set up directly. An entrypoint that refers to a
  collection of modules, the form which inadvertently worked
  previously, continues to be accepted but now emits a deprecation
  warning.

- [bug] [autogenerate] Fixed issue where dialect-specific keyword
  arguments on a ForeignKeyConstraint, ForeignKey or
  CheckConstraint, such as postgresql_not_valid, were not rendered
  for the constraints that are part of an autogenerated
  Operations.create_table() directive, nor for an autogenerated
  Operations.create_check_constraint() directive.  The
  Operations.create_table() case additionally requires SQLAlchemy
  2.0.55 / 2.1.5 or greater.

- [bug] [autogenerate] Fixed issue where, when using SQLAlchemy
  2.1, the CHECK constraint generated by a type such as
  ~sqlalchemy.types.Enum or ~sqlalchemy.types.Boolean with
  create_constraint=True would be rendered by autogenerate as
  explicit sa.CheckConstraint() entries within op.create_table(),
  in addition to the type itself which already produces that
  constraint, leading to a duplicate constraint error when the
  migration is run.

- [bug] [operations] Fixed issue where a CreateTableOp produced
  from an existing ~sqlalchemy.schema.Table using
  CreateTableOp.from_table() would emit the CHECK constraint
  generated by a type such as ~sqlalchemy.types.Enum or
  ~sqlalchemy.types.Boolean with create_constraint=True twice in
  the resulting CREATE TABLE statement when invoked directly.
