python: update PyPI publishing example

[woodruffw]

Why:

This updates the "Building and testing Python" guide to reflect the steps already documented in "Configuring OpenID Connect in PyPI", i.e. using Trusted Publishing to publish to PyPI rather than a manually configured API token.

(I don't have a linked issue for this, sorry! -- this was discussed in an email thread with @jhutchings1)

What's being changed (if available, include any code snippets, screenshots, or gifs):

I've changed the example PyPI publishing workflow to use Trusted Publishing instead of a manually configured secret. I've also tweaked the surrounding paragraphs slightly to include a link to the other GH docs page that references Trusted Publishing via OIDC, as well as to PyPI's own official docs for the feature.

Check off the following:

• I have reviewed my changes in staging, available via the View deployment link in this PR's timeline (this link will be available after opening the PR).

  • For content changes, you will also see an automatically generated comment with links directly to pages you've modified. The comment won't appear if your PR only edits files in the data directory.

• For content changes, I have completed the self-review checklist.

I created this PR from an organization fork, which (AFAICT) don't support this kind of access. I'm happy to add anybody who reviews here as a collaborator to the fork, however 🙂

NB: This removes the link to the starter workflow, since it's also currently out-of-date. I'll send a PR updating it as well.

Linkchecks are failing, for reasons that I don't fully understand:

TitleFromAutotitleError: Unable to find Page by '/actions/deployment/security-hardening-your-deployments/configuring-openid-connect-in-pypi'.

As best I can tell, that's the correct path component for the OIDC page, per https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/configuring-openid-connect-in-pypi

Edit: the previews also render the link correctly, so I'm guessing this is a CI issue.

@woodruffw Thanks so much for opening a PR, along with the accompanying context! I'll get this triaged for review ✨

[woodruffw]

Thank you @nguyenalex836! Let me know if I can help at all.

[woodruffw]

FYI: I'd suggest blocking this on actions/starter-workflows#2345, since the two share the same sample workflow and should probably be consistent with each other 🙂

[jc-clark]

Thanks for the contribution on this one @woodruffw! On our side, we'll try to get an SME review for this PR, possibly @jhutchings1 since you've already been working together on this.

Once we have the SME approval, we can help fix up the errors, and help publish.

Thanks for opening a pull request! We've triaged this issue for technical review by a subject matter expert 👀

@jc-clark The code snippet looks reasonable, and the scenarios it unblocks (namely, keyless publication of PyPI packages) are important to the community. I haven't tested it personally, but trust @woodruffw and team to have done so adequately as the maintainers of PyPI and this publication workflow.

	The example workflow below uses [Trusted Publishing](https://docs.pypi.org/trusted-publishers/) to authenticate with PyPI, eliminating the need for a manually configured API token.

@woodruffw this looks great to me, I can help merge this once the CI checks are passing! I left a couple comments which should help fix the tests. Let me know what you think.

Thank you for your input @jhutchings1!
