PR linter

PRs that change certain things should require new/changed example wing files to ensure coverage is available for the various tests that consume those files.

Feature Spec

Suggested projects to require test cases:

• tree-sitter-wing
• wingc (maybe only certain files, like the parser/typechecker/jsify)

Use Cases

Testing is often easy to forget, but for such foundational changes, we should nudge contributors to add bare minimum testing.

Implementation Notes

I think it would be interesting to look into generic tooling to support PR lints. e.g. https://danger.systems/js/

Also note we use mergify, which can also help
