`nx format:write --files=` does not use Prettier plugins

[garrettadamsss]

Current Behavior

Using the --files arg determines allowed extensions with prettier.getSupportInfo() without loading Prettier plugins. In my case, I need the prettier-plugin-svelte plugin to format .svelte files. Instead I am forced to use the prettier --write {files}. Also a warning/error would be nice for file extensions not supported or forward the error from Prettier.

Same closed issue: #21250

Expected Behavior

nx format with the --files arg should use Prettier's plugins for non default extension support.

Steps to Reproduce

2. Install prettier-plugin-svelte prettier plugin.
3. Run nx format --files={something.svelte}.
4. The svelte file will not be processed, no change in diff file.
