[#5704] Standardize You vs I in UI

[frankelsf]

Fixes #5704

Changed phrasing of specific template questions on relevant pages to match the following updates-

Question 1: Please rate the estimated contribution of your team members and yourself.
-> How much work did each team member contribute? (response will be shown anonymously to each team member).
Question 2: Comments about your contribution (shown to other teammates)
-> What contributions did you make to the team? (response will be shown to each team member).

Question 3: Your comments about this teammate (confidential and only shown to instructor)
-> What comments do you have regarding each of your team members? (response is confidential and will only be shown to the instructor).

Question 4: Comments about team dynamics (confidential and only shown to instructor)
-> How are the team dynamics thus far? (response is confidential and will only be shown to the instructor)

Question 5: Your feedback to this teammate (shown anonymously to the teammate)
-> What feedback do you have for each of your teammates? (response will be shown anonymously to each teammate)
