Errors from yaml syntax errors doesn't fail the action

[repi]

Hi, we are using the v3-preview branch and accidentally had some incorrect yaml syntax in our configuration for this action:

"t: docs 📚":
  - docs/*
  - docs/**/*
  - ./**/*.md
"a: test"
  - api/api/**/*

(note the missing : after "a: test".

This led to the following logged out failure from the action:

(node:29872) UnhandledPromiseRejectionWarning: TypeError: (s || "").replace is not a function

But the action itself didn't report that it failed, it was green, which was unexpected.

The action itself should really fail and report a failure if it runs into such a fatal error

Had the same issue when specifying actions/labeler@master instead of actions/labeler@v2 to use the any and all functionality stated https://github.com/actions/labeler/issues/73#issuecomment-639034278

My configuration looks like this

repo:
  - any: [./*]

Result Action passed, no labels added and the unhandled promise message.
