enable usage of Contact Point custom payload with webhooks

Feature Request

Currently the Grafana provider does not support sending a custom payload when creating a Contact Point that has an integration of type "Webhook".

The only block that could support a notification template would be message one, but that will only create the template in the Message field, as shown below:

When setup this way, the system that will receive the request won't accept the payload, probably due some limitation of how a notification template can be used with the Message field.

If I manually add a custom payload and associate the same notification template (which disables the message field), things works as expected.

Even though the latest provider version doesn't support a payload block, the export of the contact point generates a HCL configuration with such field (after the manual change).

We are using Grafana version v12.0.0 (4c0e7045f9), the provider version is 3.25.1.

Are you planning to have this implemented in the future? Would a pull request be acceptable in this case?

Thanks!

I believe the issue #2165 also mentions the same feature request.
