fix(core): ensure local plugin is transpiled when using index files

[Roozenboom]

Current Behavior

In some use cases the local plugins generators and executors are not transpiled, which causes an error when you execute them. see for example

This issue is introduced by this PR #29539 and is actually a regression of an error we had in NX 18, see #22958

Expected Behavior

This PR fixes this issue by updating the if statement to register the typescript transpiler when this is not done yet.
