fix(biome)!: make biome only run in projects with biome.json file (#2984

)

Closes #2980

This PR adjusts the configuration for the biome LSP to only attach if there is an existing biome.json found.

This helps prevent conflicts in ESLint projects since biome would attach and start providing diagnostics and would format files which could conflict with the ESLint/Prettier rules that are defined.
