prettier.config.js doesn't load in extension

[charlespwd]

Describe the bug
When a user has a ESM prettier config (prettier.config.js), the formatter doesn't do anything and logs the error to the "Output > Window" logs. Nothing happens and there's no feedback to the user.

Expected behaviour
We support modern prettier configs, or we gracefully handle config errors by using default configuration/error message to user.

Actual behaviour
Nothing happens and the logs are in a different log window. It's confusing as hell.
