Add a Full Release workflow to the example workflows

[jtpio]

Fixes #175

For small projects where we don't necessarily need to check the changelog, it can be convenient to make a release in one go using a single workflow.

This PR adds a full-release.yml workflow to the example-workflows folder called Step 1 + 2: Full Release. Happy to go with another name if needed.

Generally we should still encourage the 2 steps approach to allow for checking the new version numbers and changelog are correct. So it's not mentioned in the documentation for now but could be added if folks find it useful.

Here is an example run of such workflow: https://github.com/jtpio/ipylab/actions/runs/4561211046/jobs/8046913448
