* WIP: Container building changes

* Small updates

- Updated to rust 1.73.0
- Updated crates
- Updated documentation
- Added a bake.sh script to make baking easier

In the future i would like to extract the alpine based binaries and add
them as artifacts to the release.

* Address review remarks and small updates

- Addressed review remarks
- Added `podman-bake.sh` script to build Vaultwarden with podman
- Updated README
- Updated crates
- Added `VW_VERSION` support
- Added annotations
- Updated web-vault to v2023.9.1

This is a more accurate name, since these Dockerfiles require BuildKit, not Buildx.

- Split Debian and Alpine into different build matrix
  This starts building both Debian and Alpine based images at the same time
- Make use of Docker BuildKit, which improves speed also.
- Use BuildKit caching for Rust Cargo across docker images.
  This prevents downloading the same crates multiple times.
- Use Github Actions Services to start a docker registry, starting it
via the build script sometimes caused issues.
- Updated the Build workflow to use Ubuntu 20.04 which is more close to
the Bullseye Debian release regarding package versions.
