Comment 5 for bug 1842957

I updated as many of the descriptions as I could into a standard format and would love another set or sets of eyes on these. (I think/hope I removed all permissions only relevant to PINES). I formatted in asciidoc in this Google doc: https://docs.google.com/document/d/1F2xZb9EbJjGhv-QZif0UPp7crDy-gypx5ld7k6qr-Uk/edit?usp=sharing.

Some permissions do still have their name as the description, as I have not been able to confirm what they do exactly. Permissions that were documented as being deprecated, I used 'no longer applicable' as the description.

This list was previously included in the documentation from 2.1 as an appendix, so I can plan to add it as an Appendix C to our current docs, but very open to other suggestions!
