I tested that making a prettier.config.ts, and then importing it like import('./prettier.config.ts') works directly using --experimental-strip-types. But I only tested it as a standalone script - I am unsure how to test it with prettier. I modified the functions, but I do not really know how to test it, or how to add this flag if a ts file is detected? or the users should add the flag themselves before running prettier? If the flag --experimental-strip-types is present, the current loadJs function will simply work with typescript files too.

Add flag here should be able to test

Reverted the unnecessary changes and added the flag, let me know if there is anything else to do
