Custom alert notification templates are not supported

[ankitdh7]

Problem

Currently, there is no way to customize notification templates for metric-type alerts, limiting the ability to present important information in a user-friendly format that matches existing standards.

Actual
The Coralogix platform and operator provide limited or no support for customizing the appearance and content of triggered alerts.

Expected
Users should be able to fully control the look and feel of alert notifications, ideally through the operator, allowing for notification templates to be managed using Infrastructure as Code (IaC).
