super-linter: Shellcheck Configuration File Ignored

Describe the bug

Without -x shellcheck won’t open any files that may be referenced but not explicitly passed to it on the command line. This is problematic, because super-linter invokes shellcheck once per file.

Expected behavior

I expected shellcheck not to complain simply because I sourced one script from another.

Steps to Reproduce

1. Create a bash script that sources another bash script.
2. Run super linter.
