Support Golang 1.23

[replu]

According to the documentation, this repository only supports up to Go version 1.19. v1.23 has already been released, and the go team only supports up to 1.22.
Is there a reason why support stopped at 1.19?

I've got it working with Go 1.23 no problem think they just need to update there README.

If this is indeed an Official Library, it NEEDS to be maintained at a level to support current versions. The fact that the last supported version is listed as 1.19 should mean this can no longer be called an official library. Please update for use in v1.22 at a minimum.
