[FEATURE] Allow for upvote and maybe downvote of reviews to find the most "helpful" ones

[driscoll42]

Is your feature request related to a problem? Please describe.
Generally reviews are sorted by posting time so only the most recent reviews are at the top, which is not always the most helpful.

Describe the solution you'd like
There should be the ability to upvote (and maybe downvote) reviews to all the most helpful ones to rise to the top.

Describe alternatives you've considered
Only allow upvotes to not allow downvote brigading, but I don't think that'll be a big issue.

Additional context
This is implemented on the UT Austin's MSCSHub
