Not respecting `.prettierignore`

[thernstig]

pprettier does not seem to ignore node_modules by default, but Prettier does that, see https://prettier.io/docs/en/ignore.html.

@mixer/parallel-prettier version 2.0.3 / prettier version 2.8.3

Example output when not having added node_modules to .prettierignore

> pprettier --check "**/*.{css,html,js,json,jsonc,ts,yaml}"
