feat(rome_cli): show diagnostics even when --apply-unsafe is applied

[ematipico]

Summary

Closes #4569
Closes #4633

List of changes:

• fixed the categories of the error emitted from internalError/io to a category that reflects the command run;
• changed the priority of the Severity of the diagnostics. Personally, I found 1 for Fatala bit unintuitive... so I changed it and how the lowest every is the lowest number, and the highest severity is the highest number. This help with ordering and filtering;
• fixed an issue where Rome was exiting with an error code where there were only warnings;

Test Plan

Added new test cases and updated the current ones
