Add env terraform/bicep settings schema (#11013)

# Description

This pull request introduces conversion logic and related tests for the
new `BicepSettingsResource` type in the `v20250801preview` API version,
enabling seamless translation between versioned API models and internal
datamodel representations. Additionally, it updates the
`EnvironmentResource` conversion to include `BicepSettings` and
`TerraformSettings`, and marks several dependencies as peer dependencies
in package lock files.

**API resource conversion logic:**

* Added `bicepsettings_conversion.go` in
`pkg/corerp/api/v20250801preview` to implement bidirectional conversion
between `BicepSettingsResource` (versioned API type) and its internal
datamodel, including detailed mapping for authentication registry
settings.
* Updated `environment_conversion.go` to support conversion of
`BicepSettings` and `TerraformSettings` properties in
`EnvironmentResource`.

**Testing:**

* Added comprehensive unit tests in `bicepsettings_conversion_test.go`
to verify conversion logic for `BicepSettingsResource`, including
authentication scenarios and error handling for invalid types.

**Dependency management:**

* Marked several dependencies as peer dependencies in
`package-lock.json` for both `autorest.bicep` and `generator` packages
to improve dependency resolution and avoid duplication.
