Thank you!
I just had one nit about the indexing and a question about the second test case, but this looks great.

I think we should consider a rule to get this to reduce to foo == "bar". Opening a separate issue would probably be best.

Summary
This PR closes #21692.
PLR1714will no longer flag if all members are identical. I iterate through the equality comparisons and if they are all equal the rule does not flag.Test Plan
Additional tests were added with identical members.
