docs(pm): point the governed repo set prose at GOVERNED_REPOS instead of mirroring it (#15031)

Two prose statements of the governed repo set lived outside the register
and went stale when the register grew: the pm-dispatch ACCEPT path-fork
enumerated the sibling repos by name, and the enqueue guard's header
carried a count. Both now defer to `GOVERNED_REPOS` in
`scripts/pm/check-governed-merges.mjs` — no repo name and no count outside
the register, so there is nothing left to drift and nothing to parse.
