Change "Nearby Share" to "Quick Share" in Repo Description

[karlhorky]

First of all, thanks for NearDrop, cool to see some effort at interop on macOS!

In the repo description at the top right of the page on GitHub, the current text does not mention the current name "Quick Share":

An unofficial Google Nearby Share app for macOS

Nearby Share is the old name

It would be nice to change this to "Quick Share" instead, eg:

An unofficial Google Quick Share app for macOS

Alternatives Considered

Keep both "Quick Share" and "Nearby Share" (like in the readme)

Oh I forgot about this one, done
