Lint CI is failing:

Error: The action actions/cache@v4 is not allowed in python/cpython because all actions must be pinned to a full-length commit SHA.

That's because two days we checked "[x] Require actions to be pinned to a full-length commit SHA" in the repo settings.

I'll pin the actions here and in older branches, like in the newer branches.

We already hash-pin our actions, the unpinned actions/cache is coming from pre-commit/action:

Download action repository 'pre-commit/action@2c7b3805fd2a0fd8c1884dcaebf91fc102a13ecd' (SHA:2c7b3805fd2a0fd8c1884dcaebf91fc102a13ecd)

https://github.com/pre-commit/action/blob/1b06ec171f2f6faa71ed760c4042bd969e4f8b43/action.yml#L15

They've repeatedly rejected pinning it, suggesting forking instead:

• Pin action to a commit sha pre-commit/action#177
• Pin actions/cache to SHA pre-commit/action#230
• Pin actions/cache pre-commit/action#231
• Pin actions/cache to a full-length commit SHA pre-commit/action#232
• Pin actions/cache to commit SHA for better security pre-commit/action#236

We've already switched to j178/prek-action in the newer branches, let's backport that.
