Add support for generate for alerts

[shreyas-goenka]

Changes

Adds support for databricks bundle generate alert command to generate bundle configuration from existing SQL alerts.

Why

This allows users to import existing alerts into bundles

Usage

Generate configuration from existing alert

databricks bundle generate alert --existing-id <alert-id>

This creates:

• resources/<alert-name>.alert.yml - Bundle configuration with alert settings
• src/<alert-name>.dbalert.json - Complete alert definition

Update existing bundle resource

databricks bundle generate alert --resource my_alert --force

Tests

• Added acceptance tests for successful generation and error cases

Note: It should be merged after: #3602
