update build environment to Ubuntu LTS 22.04

[displague]

Description

Update Ubuntu version and build dependencies per #43

We may need additional OS updating changes, such as in tools/build_all.sh

Why is this needed

Fixes: #43

How Has This Been Tested?

How are existing users impacted? What migration steps/scripts do we need?

Checklist:

I have:

• updated the documentation and/or roadmap (if required)
• added unit or e2e tests
• provided instructions on how to upgrade

Is there a reason we don't use the LTS?

I updated the Dockerfile locally as follows and the image works just fine:

FROM ubuntu:20.04

# Disable DL3008 as it is not possible to pin virtual packages such as qemu-kvm
# hadolint ignore=DL3008
RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive apt-get install -yq --no-install-recommends \
   ansible \
   git \
   qemu-kvm \
   qemu-utils \
   unzip \
   xorriso \
   curl \
   jq \
 && apt-get clean \
 && rm -rf /var/lib/apt/lists/*

Question: Why pin the version for specific packages?
