Upgrade ESLint configs to modules

[gilluminate]

Description Of Changes

fixes some configuration issues with ESLint that was problematic when opening a file from more than one client directory (eg. a file from admin-ui and a file from fides-js)

Code Changes

• upgrade all ESLint config files to more modern module (still not fully converted to new "flat" config format because that will require a lot more effort)
• Add /client root directory to VS Code's working directory to avoid errors with any root files there
• minor fixes

Steps to Confirm

• You should no longer see errors about eslintconfig and tsconfig and missing files
• Tests passing below should also help confirm

Pre-Merge Checklist

• All CI Pipelines Succeeded
• Update CHANGELOG.md
