feat(binaries): ✨ Add support for MKVToolNix and mkvpropedit

* Introduced `MKVToolNix` and `mkvpropedit` binaries to the project.
* Updated the environment check to include required status for dependencies.
* Enhanced the `Tracks` class to raise an error if `MKVToolNix` is not found.
* Modified the `_apply_tags` function to utilize the `mkvpropedit` binary from the binaries module.
