fix(git-node): do not enforce minimum wait time for release proposals

[aduh95]

AFAIK minimal wait time does not apply to release proposals, and in practice we do not delay releases if its proposal wasn't open for less than 48 hours, so it doesn't make sense to report insufficient time nor to check for fast-track labels. We also do not need approvals, but given that the bot opens the PR and the releaser can review it themself, it seems useful to still report lack of reviews as it's always better to do a sanity check on the release commit
