[MC-279157] Some report category names are improperly capitalized

The Bug:

Some report category names are improperly capitalized.

Throughout the game, the titles of buttons are normally capitalized, but this isn't always the case with the player reporting, therefore introducing an inconsistency. This may be due to these strings also being present within a list, but I think the same capitalization rules should still apply.

Affected Strings:

Before reading the table, please note the following:

Words colored in GREEN are correct.
Words colored in RED are incorrect.
