terminal: Switch to starship prompt

Switched terminal environments (bash,zsh,nushell) to starship
prompt (from pure-prompt/no prompt). Is mimicking the pure-
prompt however, so no big change visible. Needs additional
package on the system, which is added to the packages.

Some remaining issues with nushell (vi prompt indicator).
