Ubuntu 22.04 Docker image

[fruffy]

We are trying to get IPDK and the P4 target to work for github.com/p4lang/p4c.

By and large we use Ubuntu 22.04 and it appears the p4-dpdk-target does, too. To reduce build problems would like to use an Ubuntu 22.04 docker image. Is there one available for IDPK? If not, is it much work to publish one?
