Describe the bug

Setting App Settings that contain an equal sign (=) for an Azure Static Web App using the CLI truncates the setting after the first equal sign.

Command Name
az staticwebapp appsettings set

Errors:
The setting value is truncated. Only the part before the first equal sign (=) is set.

To Reproduce:

• az staticwebapp appsettings set --name {name} --setting-names StorageAccount="DefaultEndpointsProtocol=https;AccountName={account_name};EndpointSuffix=core.windows.net;AccountKey={account_key}"

Expected Behavior

• az staticwebapp appsettings list --name {name} outputs the following:

{
  "id": "{id}",
  "kind": null,
  "location": "West Europe",
  "name": "appsettings",
  "properties": {
    "StorageAccount": "DefaultEndpointsProtocol=https;AccountName={account_name};EndpointSuffix=core.windows.net;AccountKey={account_key}"
  },
  "resourceGroup": "{resource_group}",
  "type": "Microsoft.Web/staticSites/config/functionappsettings"
}

Actual Behavior

• az staticwebapp appsettings list --name {name} outputs the following:

{
  "id": "{id}",
  "kind": null,
  "location": "West Europe",
  "name": "appsettings",
  "properties": {
    "StorageAccount": "DefaultEndpointsProtocol="
  },
  "resourceGroup": "{resource_group}",
  "type": "Microsoft.Web/staticSites/config/functionappsettings"
}

The StorageAccount property is missing the part after the first equal sign (=).
