Toggle photo picker switch behaviour and tweak phrases (#5250)

* photo picker: toggle behaviour of switch and adjust phrasing for better UX

The enable state used to trigger the GET_CONTENT intent. Alter the flow
such that the GET_CONTENT intent is triggered when switch is disabled.
Adjust default value and other parts of code naming to reflect this.

The existing phrasing had a lot of tech jargon in it which could
result in the non-technical users being confused. Tweak the phrasing
to avoid such phrases.

The documentation in the website could also use some follow up
improvements.

* Adjust strings to clearly convey that location loss is a "risk"
