Remove the "core" key from the .info.yml file

I will review this MR.

MR !2 looks good to me.
So moving it to RTBC.

Thanks.

Truly, as long as the core_version_requirement value is not changed, there is no need to remove core.

It is core_version_requirement that needs to be changed, not core that needs to be re-added.
