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

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
