feat(js): deprecate simpleName option in library generator

[jaysoo]

The simpleName option is no longer useful as we've moved to using options "as provided" without transformation. Users should provide the exact name, directory, and import path they want to use.

Changes

• Add x-deprecated to schema.json marking for removal in Nx 22
• Add runtime warning when simpleName is used

🤖 Generated with Claude Code

Current Behavior

Users are confused with --simpleName with using --name AND --directory

Expected Behavior

We should tell users that only --name should be used.

✅ Clarified --name option in deprecation warnings

I've updated the deprecation warning messages in all library generators to clearly mention the --name option.

Todo List:

• Read current deprecation warnings in all generator files
• Update Angular library generator warning message
• Update JS library generator warning message
• Update Nest library generator warning message
• Update React library generator warning message
• Format code with prettier
• Commit all changes

Changes Made:

Updated the deprecation warning message in all four library generators from:

"Please provide the exact name you want to use for the library instead."

To:

"Use the '--name' option to specify the exact name you want for the library."

This makes it much clearer to users how they should specify the library name when the simpleName option is deprecated.
