Add flag to print all failures to console

[pgoslatara]

Resolves #

Problem

Currently the outputted failures are limited to the first 25. If a user wants to see more then they need to run in verbose mode which is painful to scroll through.

Solution

Adding a --show-all-failures CLI flag to remove the 25 failures limit. This is also accessible via the GitHub Action.
