ci(e2e): trigger e2e from supabase/cli beta releases

Adds a workflow_dispatch input and a `cli-released` repository_dispatch
listener so supabase/cli can run this e2e against a freshly published
beta build before the same bytes flow to the stable channel. The CLI
v2.99 archive layout change (CLI-1475) was only caught after the stable
release; with this in place a packaging-incompatibility regression on
develop fails this workflow and surfaces in the cli release run that
dispatched it.

When a version is supplied, the matrix narrows to that single CLI
version across all supported Postgres majors instead of the default
multi-version sweep.
