fix(workspace): support resolving bare specifiers to npm pkgs within a workspace (#24611)

This makes bare specifiers for npm packages work when inside a
workspace, which emulates the same behaviour as when there's a
node_modules directory. The bare specifier can be overwritten by
specifying an import map entry or package.json dependency entry.
