Added pylint-parseable formatter

[joacortez]

Description

Added a new output format called pylint-parseable that follows this format: {path}:{line}: [{msg_id}({symbol}), {obj}] {msg}.
Updated a comment in the existing pylint formatter to reflect the actual formatting generated by the formatter and updated the docs accordingly.

Motivation and Context

When trying to integrate prospector into a CI/CD tool I realized that the pylint output does not follow the same output format as when using pylint --output-format=parseable (see Pylint 3.3.3 Documentation The existing format includes the character in the output which makes it difficult for it to be used as a drop-in-replacement. I added a new formatter that uses the format mentioned in the docs. I added a new formatter to avoid make a breaking change.

How Has This Been Tested?

Since this does not affect other areas it was only tested using some existing python projects to test the output.
