Fix Prettier parser values when formatting files with paths (#13666)

Closes https://github.com/zed-industries/zed/issues/13660

Now, as intended, the parser value is passed only if configured in the
language settings.

Also, allows to format JSONC by default with Prettier and reformats Zed
settings.

Release Notes:

- Fixed Zed Prettier integration always passing parser value for files
with paths ([13660](https://github.com/zed-industries/zed/issues/13660))
