Webhook support get request method

[jarvis2f]

Hello, this is a great project, but I found some possible issues while using it today.
I saw that the configuration of the webhook supports get requests, but the request failed.

Maybe it's a problem here：

tracecat/tracecat/runner/app.py

Line 203 in 6431a85

@app.post("/webhook/{path}/{secret}")

And maybe the content-type can be arbitrary and the payload can be empty?

Hey! Thanks for raising this - we are aware the UI suggests that we currently support both POST and GET, but atm we only support POST. We definitely want to add support for GETs for webhooks soon though.

I'll take this on for the v0.0.1 release.
