The underscore for the activity_types overviews are missing, otherwise this section i feel is complete

Missing '/auth/jwt' endpoints under the auth category

Campuses is complete

Username could have a better description - suggestion: "Username of the user"
Otherwise everything seems covered

Settings is complete
Students is complete

Delete teaching period has a markdown error for the parameters table
Otherwise seems correct

[HarshitaShroff]

I have addressed the above feedback and suggestion.

Activity types: added the underscore for the activity_types overviews.
Auth: Added '/auth/jwt' endpoints under the auth category
Csv: updated the username description
Teaching_period: Updated the format for DELETE operation
