Clarify governance policy for Peers merging files in the browser subdirectory (#7215)

* Clarify governance policy on browser subdirectory

This change updates the `GOVERNANCE.md` file to clarify that
Peers may merge changes to the files in the `browsers` directory —
because those are compat data updates, not schema updates.
