Change most-read-with-deeply-read endpoint back to most-read-geo.json

[DanielCliftonGuardian]

This has been left as we were unsure if we might run another test using this endpoint. If this is not the case we could
change this endpoint 'https://api.nextgen.guardianapps.co.uk/most-read-with-deeply-read.json'; back to 'https://api.nextgen.guardianapps.co.uk/most-read-geo.json?dcr=true'.

Here:

dotcom-rendering/dotcom-rendering/src/components/MostViewedRight.tsx

Line 41 in 2275406

'https://api.nextgen.guardianapps.co.uk/most-read-with-deeply-read.json';
