fix typos on Spanish Level 1 and Level 2 short forms

[vmarchman]

On Level I:

Item says "two" -> should be "uno dos tres" mio should be mío

On Level II:

These items have spelling/accent errors:

quiruiriqui should be quiquiriquí vibora should be víbora periodico should be periódico oir should be oír

@HenryMehta If it is easier, please let me know what files I should edit and I can make the changes.

@vmarchman I am deploying this now so should be available for you to test when you get up. If you confirm it is working I'll deploy to production
