import from a bicep file in a bicepparam file fails to build

[polatengin]

Bicep build-params command fails when extended bicepparam file imports from bicep files.

To Reproduce

consts.bicep

@export()
var someGlobal = 'someValue'

base.bicepparam

import * as consts from 'consts.bicep'

using none

param testParam1 = consts.someGlobal

test.bicepparam

using 'test.bicep'

extends 'base.bicepparam'

param testParam2 =  'someOtherValue'

test.bicep

param testParam1 string
param testParam2 string

Run dotnet run --project ./src/Bicep.Cli -- build-params ./test.bicepparam in terminal, you'll get
