Support multiple labels

[j-f1]

I’d like to be able to specify multiple labels in the configuration so the bot will close the issue if it has at least one of the labels. For example, with this config:

# .github/no-response.yml
responseRequiredLabels:
 - more-information-needed
 - needs-reproduction

any issue labeled with more-information-needed, needs-reproduction, or both would be closed after two weeks without a response.
