alertmanager Support webhook_url_file for discord config

What did you do? I use a main Discord for receiver. What did you expect to see? I want to use pre-existing K8s secret to configure Discord receiver's webhook url instead of setting that as helm value. Like slack_api_url_file, mount the existing k8s secret into alertmanager and use that file as webhook_url.

the documentation mentions the use of webhook_url_file for discord_config i was pulling my hair as to why it was not working

The configuration documentation does mention this option, but when I try to provide just webhook_url_file it complains that no webhook_url is provided, and if I provide both, it exclaims that only one is permissible.

@arichtman same here, just found out that this has been fixed in #3728 but it hasn't been released yet.
