[FR]: Prettier for yaml formatting

### What is the current behavior?

yamlfmt, the current yamlfmt has some clear issues, such as
https://github.com/google/yamlfmt/issues/185
https://github.com/google/yamlfmt/issues/264
This makes it an unstable formatter.

### Describe the feature

I would like to add prettier as a formatting option for YAML, as it does correct formatting and already supports it https://prettier.io/blog/2018/07/29/1.14.0.html.

No files, tests, or entry points are named. Start by tracing the existing yamlfmt YAML formatter integration and reviewing the linked yamlfmt issues alongside Prettier's YAML support. Done means users can select Prettier as a YAML formatting option and the repository's relevant checks cover it.
