Cycle through Search History with up/down arrows

[danieltomasku]

Feature Description:

One helpful feature of VS Code is the ability to use the up/down arrows to cycle through your search history within search inputs. Looks like this can be done from most components that leverage search, e.g. global search, within-file search, terminal search, etc. It would be great if Theia could have this as well since currently there is no way to access previous search queries!

(It's hard to tell from the video above, but I am using the up/down keys to access previous searches)
