[PR] Change wording on the landing page - ‘Coworkers’
[PR] Change wording on the landing page - ‘Coworkers’

Summary:
Currently, on the landing page it reads:
‘Flow can help prevent bad rebases. Flow can help **protect** your carefully designed library **from your coworkers**.’ (Emphasis mine)

I do not want to protect my library from coworkers. I want them to be able to quickly and safely contribute.

In this PR I suggest ‘protect […] from errors’. However, I'd be happy with other changes.
