ci: Packit configuration update (#799)

Primarily some cleanups:
- Moved how the [copr
projects](https://copr.fedorainfracloud.org/groups/g/scikit-build/coprs/)
are handled. This should make it more usable if people want to use the
projects to check if the spec files build well
- Retire `scikit-build-core` project, instead use the auto-generated
project by packit
- Make sure `nightly` project is well ordered (previously they had the
same NVR (name-version-release) so it would pick randomly any build from
there)
- Disabled `rpminspect`. I will look into unifying with downstream's
implementation
- Cleanups in `packit.yaml` to make it simpler
- Added epel-10 as a build target
- Removed `python3-scikit-build-core+pyproject` sub-package since it
really has no effect now
- ~~Included `hatchling` tests to the test environment~~. Postponed
because F40, F39 does not satisfy requirement

---

Ideally we would want both epel-9 and epel-10 as build targets with
tests enabled, but there are some issues encountered:
**epel-10:**
- Missing test dependencies (may be satisfied later on)

**epel-9:**
- Build failure because `setuptools-scm` can't determine version from
git-archive (can be workaround)
- `exceptiongroup`: not packaged
Further blocked by `flit-scm` -> `setuptools-scm` -> `setuptools`, the
last being a major blocker for a lot of stuff getting on EPEL9
- `packaging >=21.3` vs `20.9`
- Missing test dependencies
