MigrateGraphToSQL comment incorrectly describes it as test-only

[s1ns3nz0]

The comment on MigrateGraphToSQL says the function is currently called only from tests and will be called from the main lnd binary once the migration is fully implemented and tested.
However, in config_builder.go, when DB.UseNativeSQL is enabled and DB.SkipNativeSQLMigration is false:

1. The graphMig callback calls MigrateGraphToSQL.
2. This callback is assigned to the graph migration's MigrationFn.
3. The migration list is passed to NativeSQLStore.ApplyAllMigrations.
   This appears to make the function reachable from the main lnd binary when the graph migration is pending.
   The same comment and call path are present in the released v0.21.4-beta tag, as well as on master. The links above reference the release tag so the relevant code is tied to a specific version.

Am I understanding this call path correctly? If so, would removing or updating the test-only note be appropriate?
