Go maintainers started to unconditionally update the minimum go version
for golang.org/x/ dependencies to go1.23, which means that we'll no longer
be able to support any version below that when updating those dependencies;
> all: upgrade go directive to at least 1.23.0 [generated]
>
> By now Go 1.24.0 has been released, and Go 1.22 is no longer supported
> per the Go Release Policy (https://go.dev/doc/devel/release#policy).
>
> For golang/go#69095.
This updates our minimum version to go1.23, as we won't be able to maintain
compatibility with older versions because of the above.
