chore: do not trigger release when only tests file are updated

[ryanking13]

I often found that updating runtime-sdk triggers workers-py release, because of updating the cli/tests directory. This prevents it.

[ask-bonk]

The change is straightforward: it adds "!tests/**" to the path_filters for the CLI's semantic release commit parser, so that commits touching only files under the tests/ directory won't trigger a release.

The logic is correct — path_filters in python-semantic-release supports negation patterns with !, and "!tests/**" will exclude any file under the tests/ directory from being considered when determining whether a commit should trigger a version bump.

The change is minimal, targeted, and the motivation (preventing spurious releases when only test files change) is sound. No bugs, no security concerns, no backward compatibility issues.

LGTM
