Check Code checks code even if it hasn't changed

[davidvandusen]

Expected behaviour

The api and webapp ESLint and Prettier checks (and any other module specific checks) only run when files from those modules have changed.

Actual behaviour

ESLint and Prettier run against both api and webapp even if no files from those modules have changed.

Details and resources

If the code checks were broken out into separate workflows, a paths filter could be used to determine whether they should run.
