Linter update

[benjaminJohnson2204]

Changes

• I updated the linters to use the new TSE linters, and added the secret scanning tool created by Justin.

Testing

• I ran the project, lint checks, and secret scanner, and verified that they were working as desired. Specifically, I ensured that the .env.example file didn't trigger the secret scanner, and that adding an actual secret into our source code did trigger the scanner.

Confirmation of Change

• Run the project, and it should still work fine. The secret scanner should complete without errors. If you add any of the real environment variable values from our .env file to the source code, then run the secret scanner, you can see that it detects the secret.
