fix(prettier): update configuration to latest

Updates Prettier configuration to latest version, where a few deprecated
options have been renamed.

This also changes some defaults, so remember to re-run:

    yarn d2-style apply

And commit the results with for example:

    style(format): apply latest code style

config/prettier.config.js
