[bug] v3 doesn't indicate the presence of an output value

[isaacsanders]

What happened?

for v3, the output download-path isn't defined in the action.yml. This is causing an issue when linting out workflows in GHES (source: rhysd/actionlint#442). I don't know how to add the value in the v3 branch of the action, but that is needed for those of us who can't use v4.

What did you expect to happen?

I would expect the output to be listed.

How can we reproduce it?

Run rhysd/actionlint on a workflow using the output of the v3 action. It will incorrectly raise a linting issue.

Anything else we need to know?

No response

What version of the action are you using?

v3

What are your runner environments?

self-hosted, linux

Are you on GitHub Enterprise Server? If so, what version?

v3.8+
