As a reviewer,
I want to see what languages a PR uses,
So I can home in on things I can review.
Given a PR that uses languages X, Y, and Z,
When I submit it,
Then the system should discover and record that it uses X, Y, and Z,
And when it is listed or displayed, it should show that it uses X, Y, and Z.
