containerd version 1.7.2 requires at least Go 1.19 to be built. In Focal and Jammy, the greatest version of Go available is 1.18. Since we already have Go 1.20 in Mantic, let's backport it to Focal and Jammy (containerd 1.7.2 has been built against this version in newer releases), since in the near future upstream should move to 1.20 and this will avoid one more backport of Go.
