ci(docker,workflow): install bash in images, keep /bin/sh POSIX, and simplify PR test-build deps (#4879)
# Description of Changes

This pull request updates the Docker setup for all image variants
(`Dockerfile`, `Dockerfile.fat`, and `Dockerfile.ultra-lite`) to improve
shell compatibility and ensure consistent behavior across environments.
The most important changes are grouped below:

Shell compatibility improvements:

* Added installation of `bash` and created a symlink from `/bin/bash` to
`/bin/sh` to ensure scripts expecting `bash` work correctly in all
Docker images. (`Dockerfile`:

`Dockerfile.fat`:

Default shell consistency:

* Added a symlink from `/bin/busybox` to `/bin/sh` after setting user
permissions to ensure the default shell remains available and consistent
for system utilities. (`Dockerfile`:
