Approval/Upvote should not reset the 72h timer
If a developer (author's Gitlab role) MR is only reviewed in the interval between 48 and 72 hours, the bot resets the timer (to 24h) hours even if the review is in favor of the proposition (an upvote or an approval).
In this case (upvote/approval as the only activity on the MR, 72h after the creation time of the MR version), the bot should probably ignored the timer reset and put the MR in accepted after 72h.
This should probably apply to upvote/approvals that are pushed after the 72h of inactivity. Right now, the bot switches the MR from Accepted to Acceptable, which seems unnecessary.
