Change wording of indentation coding standards

The documentation says to use indentation consistent with the main language of the **File**. But in a Twig template, that language is going to be Twig. This PR changes the wording to indicate that the indentation rules inside tags should be consistent with the main language of the **Project** Twig is being used within.
