[Bugfix]: CI issues

[general-kroll-4-life]

Background

In no particular order:

1. Windows CI skips all postgres client tests because stackql server seems not to be serving on robot test runs.
2. Following the addition of robot test Export Materialized View and then Access From RDBMSs, same test only repeateddly fails on arm64 docker buily only with message: Post "https://localhost:1091/": dial tcp 127.0.0.1:1091: connect: connection refused. Same test works fine on amd64 docker build. This has been patched by skipping robot tests on arm64 build.
3. Chocolatey downloads are hideously slow.
4. Docker builds are hideously slow.

Acceptance Criteria

1. Fix windows robot tests, or document why they need to be skipped.
2. Fix arm64 docker robot tests, or document why they need to be skipped.
3. Speed up or cache-accelerate chocolatey installs, or document why they are so terribly slow.
4. Speed up or cache-accelerate docker builds, or document why they are so terribly slow.
