Relevent log files

go: github.com/pact-foundation/pact-go/v2@2.0.4: invalid version: unknown revision 2.0.4

fix:

# install pact-go as a dev dependency
go get github.com/pact-foundation/pact-go/v2@v2.x.x
# install pact-go as a dev dependency with go install:
go install github.com/pact-foundation/pact-go/v2@v2.0.4

# NOTE: If using Go 1.19 or later, you need to run go install instead 
# go install github.com/pact-foundation/pact-go/v2@2.x.x

# download and install the required libraries. The pact-go will be installed into $GOPATH/bin, which is $HOME/go/bin by default. 
pact-go -l DEBUG install 

# 🚀 now write some tests!

Thanks, I've updated it now (removed the specific version identifier as it's not needed)
