Sending a payload, then an empty payload on an KeepAlive connection still has the old payload

[Badgerati]

Describe the Bug

If you make two requests to an empty, using KeepAlive, and the first request has a payload but the second doesn't; the second request will retain the payload of the first.

Steps To Reproduce

Steps to reproduce the behavior:

1. Make a request with KeepAlive with a payload
2. Make the same request, but no payload

Expected Behavior

The second request should not have anything in $WebEvent.Data, but it does.

Platform

• OS: Windows
• Versions:
  • Pode: v2.2.3
  • PowerShell: v7

Additional Context

This was found while documenting Pode.Web. The error is in PodeHttpRequest.cs line 48. The body will only be reset if there is a RawBody, this should return string.Empty if there is no RawBody available.
