Fix update_issue.py to parse azpysdk log format instead of deleted tox script

The get_build_info function was referencing eng/tox/run_pylint.py which
no longer exists. Updated to parse the dispatch_checks.py grouped log
format (##[group] markers) from the 'Run Tests' CI task instead of the
old tox 'Run Pylint Next' task.
