RTK Query examples broken due to misformatted tsconfig.json files

[jacklin213]

Commit b0ce4df in #4135 ended up formatting tsconfig.json files throughout the repo and appended trailing , which is not valid JSON.

This is causing examples in code sandbox on https://redux-toolkit.js.org/rtk-query/usage/examples to fail with

Error
We weren't able to parse: '/tsconfig.json': Parse error on line 18:
...  "noEmit": true,  },}
----------------------^
Expecting 'STRING', got '}'

Suggest to exclude any .json files from being formatted with trailing commas
