Fix REST API documentation for changes' sortkey parameters
To fetch previous changes, the upper case `P` parameter has to be used
according to QueryChanges instead of lower case `p`. Similarly, upper
case `N` instead of lower case `n` is required to fetch next changes.
Simply adding an alias to allow both cases of the letters to fetch
required changes is not possible, as lower case `n` is already an alias
for the limit parameter.
