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. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
