Fix typos/grammar in README.md and GOVERNANCE.md
I noticed one typo in GOVERNANCE.md, and that piqued my interest enough to squash a few more too.
Feel free to mention any that I might've missed.
GOVERNANCE:
- clients configure their surfaces. (L61)
-
ifif (L75) - merge in_to_, as per Gitlab's own terminology (L98)
README:
- protocols have phases (L15)
- added to the
staging/
directory (L34) - different protocol extension altogether (L40)
- missing commas and them (L61/62)
- added a link to GOVERNANCE.md just like it's done elsewhere (L246)
