[typo] Change developement to development

[João Neto]

Hello guys,
I beg your pardon, the main branch for development being called development. Fix this typo 😄

I suggest that the branch will be called development and master to use gitflow

Hi,
The branch developement contain deprecated code, and must be renamed. And development must be default branch
