Test scripts for the Align DAO have a problem with grep version on mac

[metronome12]

grep -P is doesn't work on a mac.

The solution to this is to install gnu grep with:

brew install grep

and then used ggrep in the scripts instead of grep.

Thank you about this, have you finally got through the test?

I will consider using "radix engine" and "scrypto unit" rust package for unit testing in future version.
