Replace gnu-bash-wrapper with kibposix and update build workflow

Removed the gnu-bash-wrapper package and replaced it with the new kibposix package, including all relevant files and documentation. Updated neofetch dependencies to use bash instead of gnu-bash-wrapper. Added a GitHub Actions workflow to build Bash for Windows using Cygwin and commit the compiled binaries to a dedicated branch.
