release notes: the 5.1.0 popup, and dataforest cloud in Settings > About

The release popup now shows 5.1.0: place search, shared place details
and faster routing as three cards side by side, each with its own
drawing. The support band is set as a card like the promise above it
(optional supportLabelKey; a release without it keeps the plain line),
and the two support buttons get the same glass look in their colours.

Settings > About gets a full-width panel for dataforest cloud, who
sponsor the servers behind place search, address search and routing.
Both logos ship in client/public/brands, so opening Settings reaches no
third party. Wherever a line names dataforest cloud it links to
https://cloud.dataforest.net/?mtm_campaign=trek, the link dataforest
gave us; the README moves to it too.

All 28 locales carry the new copy, and the old 5.0 card keys are gone.
