Support MPAs / prerendering

[xavierchanth]

I setup prerendering but convex keeps serving the same index.html file for EVERY route, even with spa fallback turned off.

What I mean by this is my dist/ looks something like:

/index.html
/foo/index.html
/bar/index.html

This code:

registerStaticRoutes(http, components.selfHosting, {
  pathPrefix: "/",
  spaFallback: false,
});
registerStaticRoutes(http, components.selfHosting, {
  pathPrefix: "/foo",
  spaFallback: false,
});
registerStaticRoutes(http, components.selfHosting, {
  pathPrefix: "/bar",
  spaFallback: false,
});

has the following behavior:

/ -> renders /index.html
/foo -> renders /index.html
/bar -> renders /index.html
/foo/index.html -> 404
/bar/index.html -> 404

Whereas I would like the behavior:

/ -> renders /index.html
/foo -> renders /foo/index.html
/bar -> renders /bar/index.html

Made a prototype for a new flag here, but it's not tested:
