prerelease option breaks install in pyyaml

[tmorrell]

Package version (if known): v8

Describe the bug

I'm unable to lock packages and Install InvenioRDM because of the allow_prereleases = true option. Pyyaml has known issue with cython 3 yaml/pyyaml#601, which results in a AttributeError: cython_sources during package locking.

Steps to Reproduce

1. invenio-cli init
2. invenio-cli install
3. Locking fails with AttributeError: cython_sources

Expected behavior

Packages lock and InvenioRDM install

Additional context

I'm running python 3.9 on a M1 mac installed via homebrew.

Just mentioning to narrow possibilities: on linux (ubuntu) with python 3.8 things are ok. So 3.9 / m1 mac are more probable cause.

My best guess is this issue is related to the M1 and homebrew python. I've switched to the 3.9 universal2 python.org installer and package locking is fine.
