New Features from 0.25.2 release of cel-spec

[slott56]

This has a new set of .textproto files, and revised .feature files.

The tags.toml is updated to flag new cel-spec test cases as "work-in-process" with the @wip tag on the tests.

The objective is to have a clean separation of features that may (or may not) pass acceptance tests. See https://github.com/cloud-custodian/cel-python/discussions for some discussion topics on how to address the WIP tags.

This also adds a refresh_spec.py script to gather some GIT log details to pinpoint exactly which commit to the cel-spec repository was used to extract test cases. The Makefile is also tweaked to create a git.log file that tracks the version details.

The refresh_spec.py script addition is a nice touch — having automated GIT log aggregation for tracking cel-spec version alignment will make it much easier to stay in sync with upstream spec changes over time. The @wip tagging approach via tags.toml is also a clean way to separate tests that are aspirational vs. currently passing, rather than just skipping them entirely. Looking forward to seeing these features land!
