docs: fix broken links in doc

[Parkerhiphop]

Description

I replaced all broken links identified in the CI pipeline run 20103076261.

Specific changes:

• docs/tutorials/github_actions.md: Removed the reference to the missing ./scripts/publish script. I updated the example to use poetry publish --build directly, matching the actual pythonpublish.yml workflow.
• Updated various other broken links in README.md, faq.md, and writing_commits.md.

However, the Continuous delivery made easy (in Python) in docs/external_links.md is a member-only post, so it would be 403 Forbidden.

Should we remove it or keep it?

Hi @Parkerhiphop , thanks for improving our documentation!

However, the Continuous delivery made easy (in Python) in docs/external_links.md is a member-only post, so it would be 403 Forbidden.

Should we remove it or keep it?

Let's keep it and I will add it to the whitelist in the pipeline.
