Ignore CODEOWNERS file

[coliff]

Is your feature request related to a problem? Please describe.
I have a CODEOWNERS file in my projects. The first line I have is a comment formatted like this:

# About CODEOWNERS - <https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners>

The second is a catch-all formatted as this:

* @username

As such, VS Code auto-detects the sort of file the CODEOWNERS file is and assumes it's markdown... so Prettier autoformats and changes the * @username to - @username (as it thinks its a list) - this causes the CODEOWNERS file to not work as expected.

Describe the solution you'd like

Ideally it'd be good if CODEOWNERS could be added to a global ignore somehow.

Describe alternatives you've considered

I know we can add CODEOWNERS to our own .prettierignore files for now, but a global fix would be welcome!

Using prettierignore is the correct way of doing this. THe extension is not opinionated about this type of thing.
