Allow to overwrite GitHub comment instead of creating a new one

[joshua-lehmann]

Issue:
If you create a pull request with the default action azure/webapps-deploy@v2 it will deploy and post a comment like this to the PR:

Every time you push, there will be a new comment added, meaning if you push 10 times you will get 10 comments all looking the same.

Expected/Wanted Behaviour:
Allow to set an input parameter like overwriteComment which can be set to true/false and if set to true the previous comment should be replaced.
An alternative solution could be that you create a disableComment input and let the user handle the comment by himself by providing the webapp URL as action output and then using other GitHub actions or the API t.
