client_golang depends on this ; have they / will they also bump the go version requirement?

Added client_golang maintainers to this.

IIRC we are usually trying to support the last three Go minor releases. From that perspective, Go1.19 would be fine once Go1.21 is out. But I might misremember, and I'm pretty sure it was always a best-effort thing. (Although it's usually easy with build tags etc. to maintain backwards compatibility even if using more recent Go features.)

@beorn7 We used to do that, but recently we have been only trying to support only what Go officially supports.

I guess @bwplotka and @kakkoyun should confirm or deny…

Ok, I added Go 1.18 back in.

I still want to get sign-off from both client_golang and prometheus maintainers.

I won't have access to a computer until Sunday. If it's urgent, leaving the decision to @bwplotka

LGTM, thanks for keeping 1.18 in, not big harm here to keep it IMO.

Thanks!
