complete the release note template (#637)

i've started writting the [release note for
0.86.0](https://github.com/nushell/nushell.github.io/pull/1071) and
thought we could enhance the template for the note even further:

- add some TODOs to make sure we don't forget anything
- make the `NOTE` a real note in the first section, it's just for
prettier rendering
- add some template tables in the "hall of fame"
- ❗ add a table of content to allow jumping back and forth
more easily when the note starts to get big
