avm-res-network-natgateway 0.4.0: breaking changes

Breaking changes listed in the release notes:

• Telemetry now uses an empty Azure deployment at the active subscription scope instead of ModTM. When telemetry is enabled (the default), the identity needs Microsoft.Resources/deployments/read, write, and delete at that scope. Set enable_telemetry = false to opt out.
• The minimum supported AzAPI version increases from 2.4 to 2.12. The Interfaces dependency moves from 0.5.0 to 0.9.0.
• Legacy telemetry state is forgotten using removed blocks with destroy = false. Keep the old providers available for the first initialization against an existing state, and review the upgrade plan before applying.
• The root and default example dependency tree no longer require ModTM. Two unchanged official Avm.Authoring 0.45.0 pre-commits, lint, validation, and all ten hosted PR-check steps passed at the tagged commit. Unit and integration suites are absent; no deployment, E2E, or real-state upgrade was run.

1. Breaking changes listed in the release notes for 0.4.0: 4. HashiCorp recommends explicitly constraining the acceptable version numbers to avoid unexpected or unwanted changes.
2. Check the version argument of the module block that installs avm-res-network-natgateway from the Terraform Registry. Terraform uses the newest installed version that meets the constraint. When no acceptable version is installed, it downloads the newest version that meets the constraint, so a constraint that allows 0.4.0 can bring in this release. A module block with no version argument defaults to the latest version available from the source.
3. The AVM versioning specification requires that, until a module's first major version 1.0.0 is released, the minor version is bumped for breaking changes and the major version is not bumped.
4. To stay on an earlier version for now, require a specific version. HashiCorp recommends this for third-party modules so that updates only happen when convenient to you.
5. To adopt 0.4.0, set the version argument to it, then run terraform init so that Terraform can update the local code.
