Bicep decompile Doesn't like 'metadata' resource property

[bzabber]

Bicep version run bicep --version via the Bicep CLI, az bicep version via the AZ CLI or via VS code by navigating to the extensions tab and searching for Bicep Bicep CLI version 0.4.1008 (223b8d227a) VSCode Extension version: v0.4.1008

Describe the bug When attempting to decompile the ARM template found here, I get the following error from Bicep CLI: " Decompilation failed with fatal error "[253:23]: Unrecognized top-level resource property 'metadata'""

To Reproduce Steps to reproduce the behavior: Copy the ARM template from the above link and save it as an ARM template (deploy.json). within VSCode terminal go to where you saved the deploy.json and run: bicep decompile deploy.json --outfile deploy.bicep

Same for templates, nested templates, resources...
