Is there a place you can upload your artist information once and it updates across all artist profiles from one place? (apple music,sportify,amazon,google, deezer, Allmusic) kind of like a yext for businesses or hubspot for social brands.
Honestly the best bet is a company called Xperi/TiVo who feeds metadata to a lot of those services (including AllMusic).
Please note: Xperi/TiVo does not just take in the bio provided by the artist and distribute it out, they write all of their own content.
However, album info is put in their database and distributed to many of the companies you listed.
