The bulleted list of subprojects makes it impossible to link someone to
specific info for a given subproject. Now, instead of linking someone to
sig-testing#subprojects and asking them to scroll, I link them directly
to sig-testing#kind.
While I was at this, I made the main SIG/WG/UG/Committee contact info
format match what is used for subprojects, specifically:
- display the slack channel name
- list github teams as part of contact info instead of in a table
- use - instead of * for bullets
I also removed subproject rendering from WGs, since WGs cannot own code,
and added a link to the governance definition of what a subproject is.
