This PR ensures that our init generators are hidden, such that they
don't appear in Nx Console when running generators, for example.
The init generator is meant to be used when running other generators,
like app or lib, and should not be run directly.
## Current Behavior
Init is not hidden
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Init is hidden
## Related Issue(s)
