Acknowledge existence of verbatim template tag in templatetag documentation

[Chris Jerdonek]

Currently, the documentation for the templatetag template tag ​says that you "must" use templatetag in order to display one of the syntax characters used to compose template tags:

Since the template system has no concept of “escaping”, to display one of the bits used in template tags, you must use the {% templatetag %} tag.

However, this doesn't seem to acknowledge that the verbatim tag also lets you do this. Thus, I would suggest rephrasing to something like--

The template system has no concept of “escaping” individual characters. However, you can use the {% templatetag %} tag to display one of the bits used in template tags.

I would also include a sentence at the end that reads something like--

See also the verbatim tag for another way of including these characters.

By the way, I think the "Sample usage" example in the templatetag docs might be better served by verbatim since it is a longer string with two literal bits. I think the example for templatetag might be better if it showed an isolated occurrence that doesn't have a matching pair.
