github: Update versions of action dependencies (Node.js 20).

checkout@v3, cache@v3 and setup-python@v4 are using outdated Node.js 16
which is now deprecated in GHA [1], so these actions will stop working
soon.

Updating to most recent major versions with Node.js 20.  This stops GHA
from throwing warnings in every build.

[1] https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/

While at it also updating upload-artifact version to the latest version.
Removed versions from the comment as the general behavior of this
action regarding symlinks and wildcards doesn't seem to change between
versions much.
