Fix some typos in Berry.md

I assumed heuristically en_US language.

Thanks, yes we assume en_US.

I'm ok with most changes except:

• "filesystem" instead of "Filesystem" - I don't understand why you capitalized it
• "Zigbee" instead of "ZigBee" - the camel case here is ugly and quite uncommon

Can you please change accordingly?

* "filesystem" instead of "Filesystem" - I don't understand why you capitalized it

I named it after the section name:

$ git grep -e '#.*Filesystem' -- docs/Berry.md 
docs/Berry.md:## Loading Filesystem
$ git log -n1

    Update Berry short manual

[s-hadinger]

Yes, capitalization in titles is common, but I prefer to keep it lowercase in text.

I prefer to keep it lowercase in text.

PR has been updated accordingly.
