DLP Templates that have a variable in them like ${NAME} need to be properly escaped in the TF Files

Confirmation

[X] My issue isn't already found on the issue tracker.
[X] I have replicated my issue using the latest version of the library and it is still present.

zscaler-terraformer version

zscaler-terraformer v1.2.2 Terraform version: Terraform v1.5.7

Expected outcome

Running terraform plan when there's variables as text in the notification templates errors, since they aren't escaped.

Actual outcome

Terraform commands fail:

Fail, the ${VARIABLES} need to be escaped $${VARIABLES} or terraform errors on them.
