[7.9] Add public url to Workplace Search plugin (#74991)

[scottybollinger]

Backports the following commits to 7.9:

• Add public url to Workplace Search plugin (Add public url to Workplace Search plugin #74991)

This was needed in 7.9 because none of the links to the Workplace Search dashboard from the Kibana MVP would work without it.
