core.setFailed fails if pass in an error straight from catch block

[fishcharlie]

Describe the bug

Passing an error directly into core.setFailed fails with random error ((s || "").replace is not a function).

To Reproduce
Steps to reproduce the behavior:

1. Create failing action (example below)
2. Ensure core.setFailed(e); instead of core.setFailed(`${e}`);
3. Run GitHub Action

Expected behavior

It to fail with an error message of ERROR as opposed to a type error. Both core.setFailed(e); and core.setFailed(`${e}`); should produce the same result, they aren't currently.

Example Code

const core = require("@actions/core");

(async function (){
	try {
		throw new Error("ERROR");
	} catch (e) {
		core.setFailed(e);
	}
})();

Current behavior

Other Notes

• The bug was originally found in a failing await exec.exec command. I'm pretty confident that the code above will reproduce the issue, but if not, try doing it with a failing await exec.exec command.
