Updated minor typos in index.md

I've fixed a few minor typos, see the tracked file.

I am not a native, but in computing "error" is often used as a verb AFAICT.

[svilupp]

Noted. In which case, I'll remove "error as a verb" fixes. It was distracting me during the read, but it seems to be only my problem.

I would rely on the judgement of @pdeffebach who is a native speaker here. Though, maybe your proposals are better for non-natives? @pdeffebach - what do you think?

[svilupp]

Already followed @pdeffebach 's suggestion - left only the fix from "to" --> "do", which is likely to have been a typo.

Apologies for wasting your time (and huge thank you for the amazing packages!!)

Thanks! Yes error as a verb is common, though I'm sure Milan actually wrote this.
