Update write base path URLs list to use double quotes

[akulavasu]

By default, jinja renders list elements with single quotes which causes below error when used in configmap. The changes in this PR will give double quotes for list elements.

Configuration error: Configuration error[/home/sunbird/assessment-service-1.0-SNAPSHOT/config/application.conf: 431: List should have ended with ] or had a comma, instead had token: ':' (if you want ':' to be part of a string value, then double-quote it)]
