Fix typo in 'Diversify Open Source Bangalore' on main page

Created by: Kentokamoto

I noticed a small typo under the "Spaces" section of the main page.

Originally it said "Difersify Open Source Bangalore" but I think it was supposed to be "Diversify" instead unless this was intentionally misspelled on purpose.
