Fix: remove `ConvertFrom-Json` for `/Help`

[mikaeldui]

Seems PowerShell had parsed it already.

The action was complaining about an illegal @ at the start, and it was probably caused by the string representation of the PowerShell object.

I wonder if the Epytext and Console formats could be useful for anyone, in addition to the Full format?

Would it be more correct to have files like this:

• help.json (Brief, default, current)
• help.full.json
• help.epytext.json
• help.console.json

The Brief format might not be too useful? Though I did find its compact format somewhat useful for the events.

And, what about converting /Help to the Open API and Swagger formats?

Sounds good to me to have all four, doesn't hurt, if you want to make a PR. Otherwise Ill find a time to do it later.

Also I guess the

# /Help is missing the `Content-Type: application/json` header when logged-in.

Can be removed too

Turns out that only Console has the REST related things, like explicit HTTP method and URL.
