Using ValidatePayload fails with payload signature check failed when executed using curl

[guillian-balisi]

Describe the bug

• I have a webhook receiver that I am trying to test out locally
• I have setup webhooks on buildkite and it is currently sending events. I copy the headers and payload from these events to try and test out my webhook receiver locally.
• I try to use this library and use ValidatePayload to get the payload but it always fails with payload signature check failed

To Reproduce
Steps to reproduce the behavior:

1. On Buildkite, create a new webhook notification
2. Wait for Buildkite to deliver that notification, then copy the contents of the webhook's headers and payload
3. Send that webhook with the same headers and payload using curl to your local server
4. ValidatePayload fails with payload signature check failed when using the same token as the one shown on Buildkite

Expected behavior

ValidatePayload does not fail

Additional context

Is it expected to be able to test out this flow on a local server?
