// Per documentation here- https://docs.microsoft.com/en-us/azure/azure-resource-manager/bicep/parameter-files
// parameters file should be of below format:

// "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
// "contentVersion": "1.0.0.0",
// "parameters": {
// "<first-parameter-name>": {
// "value": "<first-value>"
// },
// "<second-parameter-name>": {
// "value": "<second-value>"
// }
// }
//}
// However, azure-sdk-for-net expects parameters to be of name and value pairs:

// We'll work around the above issue by first detecting the format of the file.
// If it's in the format descibed in the docs, we'll extract the parameters value and use that for actual deployment.
// If the user chose to create a new parameters file during the deployment flow, we'll follow the format
// mentioned in the docs as a best practise.
