How to disable shellcheck integration with actionlint on MegaLinter v6

[llaville]

On official documentation of actionlint shellcheck integration we can read :

By default, actionlint checks if shellcheck command exists in your system and uses it when it is found. The -shellcheck option on running actionlint command specifies the executable path of shellcheck. Setting empty string by shellcheck= disables shellcheck integration explicitly.

If you specify shellcheck= on MegaLinter v6, you 'll get a segmentation fault.

To disable it, in your .mega-linter.yml config file, add the following line :

ACTION_ACTIONLINT_ARGUMENTS: "-shellcheck"
