fix: semantic release fix attempt

[cjumel]

Description

This PR attempts at fixing some issues with the semantic release. It also makes other CI/CD improvements.

Fixes

• I made sure the whole commit history is checked out in the CI/CD workflow (this should fix the failing job, but I couldn't test that)
• I enable a semantic release parameter to allow 0.x.x versions, to avoid bumping unwillingly to 1.0.0 (the one already set was not doing that exactly)

Improvements

• I updated the github actions we used
• I removed the tests on push on main for two reasons: even if they are failing, they are not currently preventing the release, so this is not very useful, and I enabled the settings to make sure all PRs have an up-to-date base branch, so these tests are redundant with the PRs one

Checklist

• I have run the tests locally with make install-dev and make test
• I have updated the README.md if my changes affected it
• I have updated the package version in linkup/_version.py and pyproject.toml if I plan on creating a new release
