Duplicate symbol names in a module cause fatal error in the bicep file referencing the module

[shenglol]

Bicep version
Bicep CLI version 0.2.464 (0e26cf2)

Describe the bug
myModule.bicep

param foo string
param foo int

main.bicep

// An element with the same key but a different value already exists. Key: 'foo' (Fatal)
module myModule './myModule.bicep' = {
  name: 'myModule'
  ...
}

To Reproduce
Create duplicate symbols in a bicep file and reference the file as a module in another file.
