add trailing comma fix for literals

Browse source 
This PR extends the`add_trailing_comma` fix to handle for the [upcoming support of list/set/map literals in `require_trailing_commas`](https://github.com/dart-lang/linter/pull/3340).

It's likely the tests in this PR will fail until sdk update the linter dependency to include https://github.com/dart-lang/linter/pull/3340

Closes https://github.com/dart-lang/sdk/pull/48968
