Website: Setup merge automation for this repo

[spiffxp]

I'd like to setup merge automation for this repo. This means:

Use an OWNERS file, /approve, /lgtm to allow people to merge PR's into this repo:

• If there isn't an OWNERS file, create one and populate it with people who already have write access to this repo (as approvers)
• Configure prow to turn on the "approval" plugin for this repo
• Configure prow/tide to include this repo in the tide query

/assign

Discussed during most recent sig-docs meeting, a few salient points that came up:

• existing workflow sometimes (not always) involves a Docs LGTM and Technical Review LGTM
• suggested using approved == "conforms to docs standards", lgtm == "content looks technically good", with do-not-merge/hold used to other organic workflows
• suggested using this issue to make sure we had consensus
• will make sure OWNERS/OWNERS_ALIASES are setup but won't actually enable approval+tide until I see consensus reached on this issue

@spiffxp 👋 I think we'll be ready to merge this tomorrow afternoon PST, if that works for you!

@spiffxp Any blocking issues left, or are we good to go?
