Dev environment updates

[Ickerday]

Grouping these up as none warrant a full PR.

• Update the License field from a deprecated format to a simple string
• Simplify the dependency groups
• Bump up the minimum Python version to 3.13 now that we'll be bundling it with Splunk (opt-in only for now, still - yay!)
• Bump up 3rd party package versions
• Remove non-3.13 workflows as bundling the AI module will require opting into Python 3.13 anyway

Suggested change

	requires-python = ">=3.13.0, <3.14"
	requires-python = ">=3.13.0"

Why <3.14?

[Ickerday]

That was intentional - I've had some packages scream incompatibility with 3.14 but I can't reproduce that now, so that might've been fixed in the meantime.

Suggested change

	docker exec -it splunk-instance sh -c '/opt/splunk/bin/splunk restart'
	docker exec -it splunk sh -c '/opt/splunk/bin/splunk restart'

Or has something changed that causes that?

Same below.

Suggested change

	docker exec splunk-instance tail /opt/splunk/var/log/splunk/python.log
	docker exec splunk sudo tail /opt/splunk/var/log/splunk/python.log
