Frontend: Updates Biome script

[benhammondmusic]

Description and Motivation

• moves the existing Biome work in progress action to be job in the frontend tests action
• a Biome check (without applying any auto-fixes) will run and alert the dev if the submitted frontend/src code hasn't been properly formatted using our biome settings
• it also gives some instructions on how to manually run an npm script command to apply fixes, and some suggestions on how to fix their pre-commit setup that must not be working if biome wasn't auto applied
• adds that npm script option for manually fixing ALL frontend/src files
• checks in some applied biome-fixes

Has this been tested? How?

• passing, and failing as expected when I force push a linting error
