feat(metadata): ✨ add customizable metadata delimiters for artists

* Introduced `metadata_delimiter_artist` and `metadata_delimiter_album_artist` settings.
* Updated `name_builder_artist` and `name_builder_album_artist` functions to utilize the new delimiters.
* This allows users to specify their preferred delimiter for artist names in metadata.
