fix: update Pulse scripts for v4 Go rewrite support (#6574)

* fix: update Pulse scripts for v4 Go rewrite support

- Update install script to download universal package
- Update update_script to preserve data directory during updates
- Remove Node.js dependencies and use built-in installer
- Scripts now support v4 (Go) architecture

* Update pulse-install.sh

* refactor: use community-scripts helper functions

- Use fetch_and_deploy_gh_release as requested
- Add architecture detection for multi-arch support
- Simplify update script to use helper functions
- Remove unnecessary code and keep it minimal

* fix: use correct PULSE_DATA_DIR environment variable

Changed from PULSE_CONFIG_DIR to PULSE_DATA_DIR to match
what Pulse v4.0.3 actually uses. The default is /etc/pulse
anyway, but being explicit ensures consistency.

* fix update

* fix install

* address review comments: add version file creation

* remove

* fix: update version file after successful update

* Update pulse.sh
