`pyrefly suppress --remove-unused` is not working

[rexledesma]

Describe the Bug

From https://pyrefly.org/en/docs/error-suppressions/#upgrading-pyrefly-and-other-changes-that-introduce-new-type-errors,

[...] pyrefly suppress --remove-unused is equivalent to pyrefly check --remove-unused-ignores.

This statement is not currently true. pyrefly suppress --remove-unused does not actually remove unused errors.
