BICEP BCP079: This expression is referencing its own declaration, which is not allowed.

**Bicep version**
Bicep CLI version 0.4.1008 (223b8d227a)

**Describe the bug**
When decompiling an ARM template, I see a number of warnings in output.

BICEP BCP079: This expression is referencing its own declaration, which is not allowed.

This warning is confusing and not sure how to act on it other than deleting the description.

I would expect that Bicep understands the @description metadata tag or has some way of creating a custom attribute for this.

**To Reproduce**
Each line has a description.

```arm
"parameters": {
"workspaceName": {
"type": "string",
"metadata": {
"description": "Specifies the name of the Azure Machine Learning service workspace."
}
},
```

```bicep
@description('Specifies the name of the Azure Machine Learning service workspace.')
param workspaceName string
```

**Additional context**
#1665 may relate.

No source file or test is named. Reproduce decompilation with the ARM parameters metadata.description example, compare it with the shown Bicep @description output, and review related issue #1665 and the existing discussion. Done means the description no longer produces a confusing BCP079 warning, or the expected handling is clearly documented.
