Subject: [PATCH] Editor: Correctly load RTL stylesheets for non-core blocks.

If `SCRIPT_DEBUG` is disabled, `register_block_style_handle()` loads core blocks' styles with the `.min` suffix, while non-core ones never use the minified files, but the suffix was still mistakenly included in the `-rtl` file lookup.

This commit updates the logic to match the style path set earlier in the function, ensuring that RTL stylesheets are loaded properly for both core and non-core blocks, with or without `SCRIPT_DEBUG`.

Follow-up to [49982], [50836], [54330], [55486].

Props david.binda.
