Confusing module description in README

[joeldemars]

The README contains a line that says:
The following features enable on an AOSP custom ROM using pixel's system UI with gapps installed post module installation.
I misinterpreted this to mean that you should install Gapps after installing the module, which conflicts with how the Gapps distributors say to install Gapps immediately after flashing the custom. Eventually I realized that I was reading the sentence wrong.
