Switch Fedora tests to something newer

[frenzymadness]

Currently, we cannot run tests for Fedora 35 here because the docker we have on Centos 7 is too old. @phracek do I understand it correctly that the only thing we need to do is to switch this

s2i-python-container/.github/workflows/docker-tests.yml

Lines 16 to 21 in 6dddc3a

	- tmt_plan: "fedora"
	os_test: "fedora"
	context: "Fedora"
	compose: "CentOS-7"
	tmt_url: "http://artifacts.dev.testing-farm.io/"
	tmt_repo: "https://github.com/sclorg/sclorg-testing-farm"

to Centos stream 9: https://github.com/sclorg/sclorg-testing-farm/blob/main/plans/c9s.fmf ?
