[N/A] make install script fully automatic (#384)

## Change Overview

Resolves #381. Now no user input is needed during the portion of the install script that installs `bosdyn_msgs`. 

## Testing Done

- [x] uninstalled `bosdyn_msgs` packages locally and verified that when running the install script on main I was prompted for a `y`
- [x] running the install script on this branch does not prompt me for `y` and successfully installs `bosdyn_msgs` packages

I needed the `--nox11` flag as when piping in the `yes`, as by default this opens another terminal session that doesn't register anything before the pipe.
