Run zizmor in CI, and fix most warnings (#14844)

## Summary

A [recent exploit](https://github.com/advisories/GHSA-7x29-qqmq-v6qc)
brought attention to how easy it can be for attackers to use template
expansion in GitHub Actions workflows to inject arbitrary code into a
repository. That vulnerability [would have been caught by the zizmor
linter](https://blog.yossarian.net/2024/12/06/zizmor-ultralytics-injection),
which looks for potential security vulnerabilities in GitHub Actions
workflows. This PR adds [zizmor](https://github.com/woodruffw/zizmor) as
a pre-commit hook and fixes the high- and medium-severity warnings
flagged by the tool.

All the warnings fixed in this PR are related to this zizmor check:
https://woodruffw.github.io/zizmor/audits/#artipacked. The summary of
the check is that `actions/checkout` will by default persist git
configuration for the duration of the workflow, which can be insecure.
It's unnecessary unless you actually need to do things with `git` later
on in the workflow. None of our workflows do except for
`publish-docs.yml` and `sync-typeshed.yml`, so I set
`persist-credentials: true` for those two but `persist-credentials:
false` for all other uses of `actions/checkout`.

Unfortunately there are several warnings in `release.yml`, including
four high-severity warnings. However, this is a generated workflow file,
so I have deliberately excluded this file from the check. These are the
findings in `release.yml`:
