refactor(oxfmt): Minimize populate options for Prettier (#18022)

To invoke Prettier, there is a function that performs mappings to `populate_prettier_config()` results based on Oxfmt's defaults and `.editorconfig` values.

However,

- Doing this for every field would be wasteful,
- Now, it's mostly the same as Prettier's default settings
  - Except for `endOfLine: auto`

So it has been kept to the absolute minimum.
