Add formatted examples to config file page

[connorshea]

On the configuration file page of the website, add a section that is collapsed by default under the "Options" section which shows example output for each of the different format options: GitHub, GitLab, junit, etc

This way users can more easily find out what each formatting option looks like and choose the one they prefer for their use case.

some outputs can be found in the fixtures folders, examples:

• checkstyle
• github

The complete list can be found in the source code with some unit test:

oh this page is generated automatically from the doc comments in oxlint 😬 This might actually be difficult to implement inline, maybe we should have it as a separate page? https://github.com/oxc-project/oxc-project.github.io/blob/455eff6fed8067a240a9525ee879400c8126a06c/src/docs/guide/usage/linter/config-file-reference.md

Actually I guess it shouldn't be too bad, looking at the way other sections of the page are done. But this change will need to be made in the oxc repo.
