Subject: [PATCH] fix(js): use uuid when generating tmp tsconfig (#30118)

## Current Behavior
When multiple processes/tasks are running in parallel for a single
project that produce tmp tsconfig files for buildable libraries, they
can clobber each other.


## Expected Behavior
Ensure the config file is generated with a unique id to prevent
clobbering
