Optional inputs are not defined

[jaredmcateer]

Using the optional inputs results in a warning:

Warning: Unexpected input(s) 'title-regex-flags', 'error-message', valid inputs are ['entryPoint', 'args', 'title-regex']

I assume this is because they are not present in the actions.yml file but I am inexperienced with writing github actions.

I'm also running into this issue. It seems like the error message does work, however.
