Update minor versions of *many* dependencies.

Closes #DNE

What's Changed

Essentially this is a manual attempt at addressing #4564, albeit targeted to develop rather than next (Since all dependency bumps in here are minor versions, I'm of the opinion that this should be acceptable in a patch release).

In addition to not including any major version bumps (see #4616), this also omits the following updates that had been proposed by #4564:

• djangorestframework 3.15+ (Code changes needed to update to django-rest-framework latest version #5517)
• drf-spectacular 0.27+ (Code changes needed to update to drf-spectacular latest version #5518)
• Markdown 3.6+ (currently disallowed by latest mkdocstrings-python due to unspecified "breaking changes")
• graphene-django-optimizer 0.9+ (would require a major version bump of graphene-django)

There are minor code changes included in this PR as follows:

• Selenium docker image version updates corresponding to the Selenium dependency bump
• A few whitespace changes resulting from the ruff dependency bump
• Docs changes from storages.backends.s3boto3.S3Boto3Storage to storages.backends.s3.S3Storage and similar resulting from the django-storages dependency bump (note: the old import is still supported for now but is considered deprecated)
• Integration test update to handle a new URL pattern added by the django-health-check bump
• Changes to a couple of yield statements to address a new pylint warning
• Removal of previously deprecated ExtendedManager and ExtendedQuerySet base classes from django-celery-beat (these were actually removed from the code base in the previous version before this dependency bump, but for some reason the code was still present in the published wheel??)
