Pact-5 doesn't allow loading a REPL file from the command line

[CryptoPascal31]

Issue description

"Pact legacy" allowed to launch directly a REPL file from the command line:

pact my-file.repl

This doesn't work with Pact-v5. I need to start the REPL and then:

pact> (load "my-file.repl')

This not very convenient.

Thanks for the report. Pact-5 alpha isn't exactly feature complete as a command line tool. We'll keep this open for now since we will mirror this behavior going forward.
