chore: publish to PyPI on release

[ninabernick]

Publish to PyPI on release.
https://test.pypi.org/project/platformics/
Changes:

• metadata added to pyproject.toml
• issue with biopython resolved
• upgrade asyncpg to 0.29, was having a conflict with python 3.12 downstream in the VCP app - not sure why it didn't already have it in platformics

Steps:

• add a new publisher to PyPI project through UI. This allows us to publish from GHA
• add step to build and push workflow to publish to PyPI
• set to run on dev branch, temporarily hardcode version (PyPI doesn't allow dev versions that are generated by poetry-dynamic-versioning), push to Test PyPI
• link to test commits, link to successful workflow run
• push to regular PyPI: https://pypi.org/project/platformics/#description
• revert temp changes
