Sebastiaan van Stijn 7b624841c4 update minimum go version to go1.24
Various dependencies, including "golang.org/x/.."  started to update
the minimum required version,so we should follow suit for the next
release.

Note that the `//go:build` directives not necesserily have to be
updated, but it's good to keep them in sync until we have a go.mod
to control this.
