Add task to publish comparison test results

[mranst]

Description

This PR adds a task that will copy relevant text files (namely jedi_log_comparison.txt) and plots generated by comparison suites to another location. This is intended to be used by the CI tests to publish these results to Dataportal. By default, no publish_directory is set, so this task will not do anything unless it is overridden (It also will not be run unless the comparison fails). A pending PR to CI-workflows will enable this feature for tier 2 tests.

Looks good!

Minor comment: Definitely not a required change for this PR, but take a look at Python's built-in pathlib module. It has a lot of quality-of-life improvements for working with system paths. For example, with this:

from pathlib import Path

...you can write this line as something like:

cycle_dir = Path(self.cycle_dir())
publish_location = Path(self.config.publish_directory())
if cycle_dir.is_dir():
    files = cycle_dir.glob("eva/**/*.png")
    out_path = publish_directory / self.__datetime__.string_directory() / self.get_model()
    out_path.mkdir(parents = True, exist_ok = True)

The other potential advantage of using pathlib.Path in more places is that it improves our ability to type-check places that need paths. Right now, we use str annotations for this, but pathlib.Path would be stricter (and therefore help catch more bugs earlier).

Minor suggestion on consistent usage of pathlib. Then, resolve merge conflicts, pass tests, and I think this is good to go.

I would also replace the shutil.copy calls with pathlib.Path.copy, unless there's a good reason not to. But otherwise, I think this looks good, assuming relevant tests pass.

Thanks! Path.copy is python >3.14, I'll keep that in mind for the future
