[Merge-to-stage worfklow] Increase Github APIs listReview per_page limit

[mokimo]

Description

It can happen that the merge-to-stage workflow doesn't correctly identify reviews for a PR due to limitations on the github APIs. By increasing the limit from the default 30 to 100 on the list review endpoint we should be very unlikely to run into a scenario where a PR has 2 approvals but we can't know due to pagination limits.

We ran into this on two occasions that I know of with a limit of 30, so with a limit of 100 we can be virtually "safe" from PRs preventing to get merged due to "insufficient approvals" by misdetection.
