chore(deps): update dependency ruby to v4 (#19)

* chore(deps): update dependency ruby to v4

* fix: suppress Ruby warnings and remove dead code

- Add RUBYOPT="-W0" to CI workflow and taskfile to suppress multipart-post deprecation warnings
- Downgrade faraday to 1.8.0 to avoid faraday-multipart dependency
- Remove unused dir, install-devbox, and install tasks from taskfile
