Script Loader: Correct the number of arguments passed to the closure in enqueue_block_styles_assets().

This avoids an `Uncaught ArgumentCountError: Too few arguments to function {closure}(), 1 passed` PHP fatal error when registering a block style with the `should_load_separate_core_block_assets` filter enabled.

Follow-up to [51471].
