QoL - Check version mismatch between installed Biome version and JSON-schema version

[hornta]

When running Biome in version X and the version of the $schema property of biome.json is NOT X(https://biomejs.dev/schemas/Y/schema.json), it would be helpful with a little warning somewhere in case there are unexpected configuration changes.

We recommend running biome migrate when you update Biome. However, I accept that it could be helpful to have a warning.
