Subject: [PATCH] bun-types: declare MatchedRoute.scriptSrc

Bun.FileSystemRouter's MatchedRoute prototype installs scriptSrc as a
second name for src (filesystem_router.classes.ts), but the MatchedRoute
interface in bun.d.ts did not declare it, so reading it failed to
type-check. Declare it as a deprecated alias of src, and read both names
in the fsrouter fixture that bun-types.test.ts type-checks.
