RubyGems does have gem signing, but it's not widely used.
There's a proposal for a new "one button" approach using sigstore[0].
Other ecosystems are also looking at sigstore too, and a lot of us are cooperating in the OpenSSF Securing Software Repos WG [1]. Package signing is a regular topic of discussion and there are various efforts underway.

Disclosure: I am involved with both of these.
