Why:

I found this issue, while reading the docs

What's being changed (if available, include any code snippets, screenshots, or gifs):

If you use "<whatever>" | Out-File -FilePath "$env:GITHUB_PATH" -Append you need to add an echo to the command before the pipe (|)

Yes, I also noticed this issue. We need it.

@Totto16 According to everyone I've talked to, all the documentation I've been able to find, and a Stack Overflow question someone unearthed for me, the Out-File cmdlet sends outputs to a file without the need for "echo."

Oh shit, then I'm sorry, I Just thought it doesn't make sense, since a pure string as command piped into another command isn't the same as echo "<some string>" | whatever ( at least on every "normal" shell in the world) . It didn't work for me in an github action, but it might be, that I not only added the echo, but also fixed another problem, and that was the correct fix for the error. I am not sure anymore 😓

Anyway, if you can confirm, that it also works without echo, I'll close this PR, again sorry for not checking it myself and coming to the same conclusion.

@Totto16 It's not a problem. According to Copilot (which, you know, take everything it says with a grain of salt - I started there but double-checked with multiple other people), PowerShell is unusual in this respect. I can't actually check myself because I'm on a Mac and so is most of the rest of GitHub. If you can double check that would be awesome, but if not my inquiries are still open and several actual experts have been pinged. Not sure if people are just bored on a Friday or what, but like three people jumped on this one with pings to additional people, so... 🤷‍♀️

I Just double checked it in the CI, both works (with and without echo), so I'll close this PR. Thanks for all the help.
For reference, I just ran the CI here
