Bug 22452: Fix typos in add mana comment modals

There are typos in modal where you can add a comment to mana:

'caracters' should be 'characters'
'commment' should be 'comment'

Test plan:
1) Create subscription from Mana
2) On subscription detail page: report mistake > other a modal is shown
--> without patch it reads 'Please enter a new commment (max 35 caracters)'
--> with patch it reads 'Please enter a new comment (max 35 characters)'
3) The same in mana search resultss and in reports
