don't render the minimap if it fails to initialize the gl context (#3679)

So far 33 people have had tldraw crash due to getContext('webgl2')
returning null for some reason. Maybe it's to do with what kind of
graphics hardware they have available.

This PR adds a stopgap measure wherein the minimap manager just fails to
render anything on the canvas element instead of crashing the app.
Ideally we'd have better UX around this but that can wait.

I'm gonna hotfix this to dotcom.
