Unpin h2

Closes #493

I ran the test suite locally and couldn't encounter any issues with h2>=4.

@wolfv I'm getting similar CI errors as in #495, which I don't think are related to my changes. Do you have idea what might be going on here?

[wolfv]

I am re-running CI against master, let's see what happens!

[wolfv]

Hm, unfortuntaely I do not see that same test failure on master ( FAILED plugins/quetz_harvester/tests/test_main.py::test_harvest_endpoint_and_job)

Not sure at all if it's related or not.

Thanks for re-running against master. I will take a closer look at the error again.

I also triggered master again (https://github.com/mamba-org/quetz/actions/runs/1970213557) and it didn't have this error.

This may also be some unlucky combination of circumstances...

Should we cut a release first, with the current pinnings?

Should we cut a release first, with the current innings?

Yes, that would be great! Thank you.

Checking this PR again against the main branch.

for some reason CI didn't trigger and I thought it was green ... when it wasn't. Anyways, now I am forced to look into this error :)
