I have packaged shellcheck into a form that can be executed with go run

https://github.com/wasilibs/go-shellcheck

I'd like to then specify it when running actionlint so that when debugging a CI failure, devs can copy/paste to reproduce the command without any tool installation / version mismatches.

go run github.com/rhysd/actionlint/cmd/actionlint@v1.7.4 -shellcheck="go run github.com/wasilibs/go-shellcheck/cmd/shellcheck@343642672fe6b725a201c27a742cbed0f5c5075a"

This patch seems to work well with that pattern

Is it something that could be considered for the project? If so, I'll send a PR.
