Fix requirement.txt by updating requests from 2.11.1 to 2.22

[Selich]

Our project uses Pyrebase but also use libraries that require the library to be 2.22

I can pr and fix if I have permission to do so.

This is preventing me from using pyrebase with poetry. See python-poetry/poetry#697 for more detail if you're interested in what exactly is conflicting.

Changing to requests==2.23.0 should fix the issue.

EDIT: dependabot has already created a PR! It's not to the absolute latest version, but in my case at least I just need >=2.18.0 to satisfy dependencies. Can this please be merged? #319

#260 would work as well

I'm putting in another vote for requests to be updated, as pyrebase requirements are clashing with stripe's requirements (>=v2.2.0)

[williamgueiros]

the bigger problem is 2.11.1 is release in Aug 17, 2016
and have any new versions.

in terminal now show this message.

+1 for merging Please!!!
It's crashing with other google-api-core dependencies (Requiring requests>= 2.18)
