Fix resource gallery submission workflow

[erogluorhan]

Closes #369

This PR addresses the needs due to version changes in pydantic as suggested in the pydantic Migration Guide:

• Remove the deprecated __post_init_post_parse__() and move its functionality into _get_inputs()
• Use model_dump_json() instead of deprecated dict()
• Also uses "affiliation" instead of formerly used "institution" in gallery_generator.py, resource_gallery.yaml, and collect-user-submission.py files. This change also needed the ProjectPythia/.github/PR#63

A thought: should we update the form template and card text to all use "Affiliation" regardless? It seems more broadly applicable than "Institution" and is in-line with expected fields in eg CITATION.cff.

[erogluorhan]

Yes, I agree! We can do that in conjunction with this PR

[erogluorhan]

Please see ProjectPythia/.github/PR#63

[erogluorhan]

...and also the gallery_generator.py and resource_gallery.yaml files here for "institution" to "affiliation" changes

Note to reviewers:

This PR should be complete; and input submission validation should likely be running successfully. I am not 100% sure because when I bypassed branch protections and merged a prior PR into the main (FYI: later reverted) to see the things because testing this locally is quite hard and testing without merging into main is impossible, there was a serialization error at the final line of collect-user-submission.py, i.e. json.dump(inputs, f). See this

After that, this PR uses inputs = issue.submission.model_dump_json() rather than inputs = issue.submission.model_dump().

To test similar things locally, I used a sample github event payload file that had an issue creation event in it but could not replicate this serialization issue. I suggest that we merge this into main and see how it behaves, if things still don't get validated, we can follow up with an additional PR.

Agreed! Thanks Orhan.
