Bump action versions

[camposandro]

Node 16 is coming to the end of life, in favor of Node 20. This bumps the versions of all the actions used by the template project. The workflows (except for those of PPT) are now pointing to the latest release of each action.

Some considerations

• The latest versions of codecov/codecov-action stopped supporting tokenless upload of code coverage reports. We are now required to add a CODECOV_TOKEN secret to our repositories.
• pre-commit-ci/lite-action is not on Node 20 yet but there's a PR under a review for that purpose.
• JamesIves/github-pages-deploy-action will remain on v4 because their development branch does not contain the deployed lib/.

Closes #358.

That's super unfortunate that codecov requires a token now :(
