fix(ci): use sh instead of bash for script execution in Drone CI

- Replace bash with sh for script execution to work with docker:dind image
- Add bash installation to prepare step for script compatibility
- Keep chmod +x for ensuring script permissions
- All scripts now use sh interpreter which is available by default

This resolves '/bin/sh: bash: not found' errors in Drone CI pipeline
