Ideas for streamlining our release process

• https://github.com/mne-tools/mne-python/issues/11466
• https://www.conventionalcommits.org/en/v1.0.0/
• https://commitizen-tools.github.io/commitizen/
• https://github.com/github-changelog-generator/github-changelog-generator
• eliminate names.inc and just link to everyone's GH page
• https://github-activity.readthedocs.io/

so far this is an unordered list of ideas. As things get fleshed out, would be nice to have it more structured. One idea for structure would be:

### description of a step in the release process
- name of tool that could automate it
- brief details of how it works
- any foreseen downsides
