$GITHUB_PATH support (#566)

* Regression in the .golangci.yml file

* This looks like an even better fix to #451

The previous solution only prevented the `starting container process caused "exec: \"bash\"`
error when someone added an "extra" path in the workflow using `::add-path`

* Add support for >> $GITHUB_PATH

* The newRunCommand has too high cyclomatic complexity

* Add "linux/arm64" to new test

* The cyclop linter was complaining so I extracted some funcs

* Close some readers

* Fix typo

* fix: add missing composite function

* Fix regress from merging

* Keep the error messages as is

* consolidate with master

* Close the tar reader on defer

* New way to get ContainerWorkdir

* Remove arch from runner test

* Separate the UpdateFromEnv and UpdateFromPath
