README.md - GReader Redate not required for Reeder 5 (#4413)

* README.md - GReader Redate not required for Reeder 5

Tried both as i still used Reeder 4 up until a month ago, when i installed FreshRSS. Then I switched to Reeder 5 which shows the Date and Time the corresponding Article was released.

I just commented on a corresponding Question/Issue, with Screenshots showing the difference.
