ci: use disk-space-reclaimer in build_docker workflow (#5242)

The `build_docker` job runs out of disk space with current manual
cleanup (`rm -rf /opt/hostedtoolcache`).

## Changes

- Replace manual cleanup with
`insightsengineering/disk-space-reclaimer@v1` action in `build_docker`
job
- Configure comprehensive cleanup: tools-cache, Android SDK, .NET SDK,
Haskell, large-packages, swap-storage, and docker-images

This frees up significantly more space than the previous manual approach
by removing multiple pre-installed components that consume disk space on
GitHub Actions runners.
