Antonin Godard Feb. 23, 2026, 10:57 a.m. UTC
Rework the generation of the switcher menu, and also fix it. It's not
obvious how this could be split for easier review, as many parts depend on
one another, so this is what this patch changes and fixes:

- The menu only contains branch tips versions of the documentation for
  supported releases now - even though the latest tag is displayed in
  the menu.

  This approach will fix the lack of release notes for the latest
  version of an active branch, as release notes are always published
  after the yocto-docs repository is tagged.

- Show a commit id when building on a separate commit that is not a
  branch tip or not a tag. This should only ever happen when building
  locally (not for the published version).

- All stable/LTS versions are displayed in the menu UNLESS the current
  version for which we are viewing is part of them, in which case it's
  shown last in the menu.

- Rework the logic to show outdated or obsolete versions to conform with
  the above changes, but overall it behaves the same:

  - granted that Kirkstone is an active release, and 4.0.32 is the
    latest tag for this release, the "outdated" banner is displayed if
    we browse any version of Kirkstone inferior to 4.0.32.

  - browsing any version not part of the active releases (all LTS
    versions + the stable branch) will show the "obsolete" banner.
