Document about environment variable escaping #492
Description
TL;DR
I used this action to deploy an application which interacting with the Cloud SQL. I escaped the password by wrapping with double quotes. Then I got an error when connecting to SQL. I spent some time to debug it. Then I discovered that this action is using parseKVString from google action utilities and it is escaping characters using backslashes. We can avoid such problems by clearly documenting it.
