Multiple action keywords for the explorer plug-in

**Is your feature request related to a problem? Please describe.**

with all the other plugins in flow launcher you can add a space in the middle of the 2 activation keywords and have 2 separate activation keywords for example " * ff " will make it appear in global search and using the ff to use this specifically I tried doing the same thing with the explorer plug-in and it didn't work for some reason

**Describe the solution you'd like**

Implementing the already existing future of Separating two heroes with a space " " So the plug-in get activated when either of them is used

**Describe alternatives you've considered**

didn't Consider any

**Additional context**

Start by locating the Explorer plug-in's activation-keyword handling and compare it with the other Flow Launcher plug-ins mentioned in the issue. Verify how a space-separated pair is parsed, then test that either keyword activates Explorer while the existing behavior remains unchanged.
