url.parse() deprecation warning in CI actions

[jacalata]

The following deprecation warning appears in CI logs (e.g. in the publish-pypi workflow):

(node:1958) [DEP0169] DeprecationWarning: `url.parse()` behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for `url.parse()` vulnerabilities.

This is a Node.js deprecation in one of the GitHub Actions dependencies (likely actions/cache or actions/checkout). Should be resolved by ensuring all actions are pinned to their latest versions.
