Let pip sort it out.

- Remove python3-wheel Debian package, I'm installing it from PyPI
anyway.
- Install the Debian package for pyyaml since building it seems to fail.

Maybe that will solve it.

It's unmaitained and can be easily replaced.

With the latest pip and the new resolver, let pip work it out.

It was an awscli dependency on colorama<0.4.4 and >=0.2.5.

I'm not sure why, but pip keeps trying older and older versions of
awslic and botocore. Force the version for pip.

- Use the new format for APT sources and keyrings.
- Installl the Google Cloud SDK.
- Use the full URLs for images.

For flatpak-spawn to work.

See https://github.com/containers/toolbox/issues/145 .

Add the Protobuf libaray, headers, compiler and Python pacakge.

This reverts commit 2515a8ea.

Didn't help.

I think it's fixed in toolbox, but didn't make to the 0.0.99 release.

Based on https://github.com/containers/toolbox/pull/371/files.

It used be imported via the docker template, but now it's explicit.

- Push images to the Shore image registry.
- Update template name.

Tag a few of them. Add reg.

For getting secrets out of Keepass on the command line.

Per https://github.com/containers/toolbox/#image-requirements.

I think it's causing to build to fail (only reason it seems).
