Summary:
I was confused by the current documentation, as it was requesting me to pass the previously received `end_cursor` into the next fetch but it was declared as a boolean. I checked in the debugger and it's just mislabeled in the docs, so this PR fixes the docs.
I tried to push this change back in #15472 but wasn't able to undo the borked rebase, so I'm submitting a new PR.
This is a change to documentation only.
[DOCS] [BUGFIX] [Libraries/CameralRoll/CameraRoll.js] - Corrected return type in the documentation for the `start_cursor` and `end_cursor` values.
