fix(module-federation): the module federation package depends on rspack (#30520)

## Current Behavior
The `@nx/module-federation` depends on the `@rspack/core` package but it
is currently only set as a `peerDep` meaning users need to install the
package manually.

## Expected Behavior
As the package depends on `@rspack/core`, make sure it is set as a
dependency
