I'm always frustrated when I use the Text Translator API sample code provided in the bot-builder-samples repository because the subscriptionRegion is not included in the header section. This omission leads to authentication errors when using a regional translator resource.

Description of the solution
I would like the sample code to be updated to include the subscriptionRegion in the headers. The updated code should look like this:
path of file is :
microsoft/BotBuilder-Samples/samples/python/17.multilingual-bot/translation/microsoft_translator.py
headers = {
"Ocp-Apim-Subscription-Key": self.subscription_key,
"Ocp-Apim-Subscription-Region": self.subscription_region, # Necessary if using a regional translator resource and If you are using a global translator resource, you can omit the 'Ocp-Apim-Subscription-Region' header.
"Content-type": "application/json",
"X-ClientTraceId": str(uuid.uuid4()),

}

Additionally, comments should be added to explain that this header is necessary when using a regional translator resource and can be omitted if using a global translator resource. For example:

alternatives I've considered
As an alternative, I considered manually adding the subscriptionRegion every time I use the sample code. However, this is not an ideal solution as it requires extra effort and increases the likelihood of errors.

Additional context
if not using region.

if using region.
