Summary

• New .github/workflows/publish.yml builds the wheels of a release tag and uploads them to PyPI with trusted publishing, as microsoft/autogen does. It runs when a release is published, or by hand with a tag.
• Only the upload job, in the pypi environment, gets id-token: write.
• Remove the Azure publish pipeline. For v1.64.0 it failed in npm pack of the beta driver from the DevDiv feed; the same build works from public npm.

Needs, before the first run:

• PyPI trusted publisher: owner microsoft, repository playwright-python, workflow publish.yml, environment pypi.
• A pypi environment in this repo, with required reviewers.
