ENH: Bump to 24.04 and tomllib

[larsoner]

Over in MNE-Python we get:

https://github.com/mne-tools/mne-python/actions/runs/18803456223/job/53654097297?pr=13460

  File "/check_changelog.py", line 34, in <module>
    toml_cfg = loads(pyproject_toml.decoded_content.decode('utf-8'))
Bot username: changelog-bot
  File "/usr/local/lib/python3.10/dist-packages/toml/decoder.py", line 511, in loads
    ret = decoder.load_line(line, currentlevel, multikey,
  File "/usr/local/lib/python3.10/dist-packages/toml/decoder.py", line 778, in load_line
Base repository: mne-tools/mne-python

    value, vtype = self.load_value(pair[1], strictly_valid)
  File "/usr/local/lib/python3.10/dist-packages/toml/decoder.py", line 880, in load_value
    return (self.load_array(v), "array")
  File "/usr/local/lib/python3.10/dist-packages/toml/decoder.py", line 1002, in load_array
    a[b] = a[b] + ',' + a[b + 1]
IndexError: list index out of range

So let's bump to tomllib instead of using toml, which is easily achieved (hopefully) by using 24.04 + Python 3.12 instead of Python 3.10.

I don't see anything that actually tries to run the PR'ed version of the action, so I'm going to add a CI workflow to do this first. I'll also add a dummy run first, replicating the issue (hopefully). Then once that works, I'll push a fix.

Thanks! It was a long time ago when toml people refactored an internal function that we used here, broke something, and Stuart Mumford made decision to copy the old function out because it was the fastest way to fix the incompatibility. Perhaps things are different now.

The dependency list here seems unrelated. Is this for testing?

[larsoner]

Ooof I'm messing with the wrong repo... need to do this to actions-check-changelog 🤦

The fix using Auth here is uncontroversial. So if you want to just open a mini PR with this Auth fix, we can probably merge it right away.
