Adjust upstream versions

[khaeru]

In accordance with the upstream version policy and the release history:

• Latest 4 upstream versions are 3.11 (just released), 3.10, 3.9, and 3.8.
• Earliest version released within the last 2 years (since 2023-05-27) is v3.8 (released 2024-01-12).

Thus:

• Drop support for upstream version ixmp/message_ix 3.7. (Sorry: the branch name is a misnomer/confusing. Support for 3.8 is not dropped.)
• Explicitly test support for ixmp/message_ix 3.11 in the "pytest" CI workflow.
• Bump minimum genno version to 1.25. An earlier version was only needed for ixmp/message_ix 3.8.0.
• Drop minimum_version marks for:
  • genno 1.24 and earlier, message_ix 3.7 and earlier —since these are no longer supported. Also drop any workarounds for these versions.
  • genno 1.25 and message_ix 3.8 —since these minima are now enforced via pyproject.toml.

Also:

• Adjust .util.minimum_version() to handle recursive references to other functions/callables decorated in the same way and thus their minimum version requirements.

How to review

• Transport (@r-aneeque, auto-requested as a Code Owner) and water code (e.g. @adrivinca or @awais307, same):
  • Quickly skim the diff for the respective modules.
  • Note there are no changes to function or test bodies, only old decorations removed.
• General code (@glatterf42)
  • Read the diff.
  • Note that the "pull_request" CI checks all pass; ignore "pull_request_target".

PR checklist

• Continuous integration checks all ✅
• Add or expand tests; coverage checks both ✅
• Add, expand, or update documentation.
• Update doc/whatsnew.
• (After approval) Drop the TEMPORARY commit.

Thanks, lgtm :)

To me and @Wegatriespython all looks good for the water side
