fix(info): resolve bare specifier pointing to workspace member (#27020)

Fixes https://github.com/denoland/deno/issues/26721

Previously, we were applying only the import map, which would result in
`@scope/foo` expanding to (e.g.) `jsr:@scope/foo@1.0.0`. Since that
didn't exist it would error and fail to resolve.
