docker image is run by default as root (privileged) user about tflint-bundle HOT 3 OPEN

You are right. But I'm a little concerned about the incompatibility of changing the default user...

@wata727 here is PR with the change #69 ready for review please.
Technically, inside container it runs as non-privileged user the same way.
Do you have an example of some incompatibility ?
PS: it does make sense to add in feature at least some test scenarios in CI so that we can capture broken tests for build container.

For example, the following code from Super-Linter will no longer work.

Originally, this image was not intended to be used as-is (probably too many things are missing), so a non-root user may not be necessary.
