Fenix: FNX2-15332 ⁃ Renaming "Shortcuts" to "Search engines"

[vesta0]

Let's rename search "Shortcuts" to "Search engines" based on UX recommendation.

What is the user problem or growth opportunity you want to see solved?

People may not understand that tapping the “:mag: Shortcuts” button will give them a selection of search engines to choose from.

By renaming “:mag: Shortcuts” to “:mag: Search engines”, we are labelling the feature using a name that people may be more used to hearing.

Since this should just involve string changes I'm making it as good first issue
