chore: add website governance aliases and content filter

Add sig-contribex-website-owners and sig-contribex-website-reviewers
aliases to OWNERS_ALIASES, and update the OWNERS content filter to
use the website reviewers alias.

- sig-contribex-website-owners: SIG ContribEx chairs and tech leads
  (Priyankasaggu11929, MadhavJivrajani, mfahlandt, palnabarun)
- sig-contribex-website-reviewers: lmktfy, jberkus, reylejano
- sig-contribex-en-owners: fsmunoz, TineoC, jberkus
- sig-contribex-en-reviewers: lmktfy
- OWNERS: add content/ to the static site generator filter with approvers

Follow-up to the i18n foundation PR to split governance changes out.
