Testing with supported Python versions

[candleindark]

The project's metadata indicates it support Python 3.8 to 3.12. However, it is tested only in Python 3.11 and 3.12 with Hatch

dump-things-server/pyproject.toml

Lines 102 to 103 in fa92560

	[[tool.hatch.envs.tests.matrix]]
	python = ["3.11", "3.12"]

, and only in Python 3.11 with GitHub CI

dump-things-server/.github/workflows/run_tests.yaml

Line 13 in fa92560

python-version: '3.12'

Should we update the metadata of the project of the versions Python supported by the project or test the project in additional Python versions?
