Report failed parsing

[clavedeluna]

Overview

Codetf report should include list of fails that filed to be cst parsed or codemod-transformed

Description

• previously we have been skipping reporting for a codemod if it had no results, however this doesn't really align with having a list of failed files. All files could fail so there would be no results. We should report anyway
• @drdavella I do need confirmation that this is ok with pixeebot - that a codemod without anything in changeset will still be in the report.
• we now also report fails that were either not correctly cst parsed (already handled) and not able to be transformed by a codemod (new)
• added corresponding test cases to demonstrate.

the pygoat failure may now be expected, need to investigate

Changes look good, but didn't notice the failures

[drdavella]

Overall looks great but I want to hold off on the one behavior change you introduced for now.
