Feature request: Add text element support

[a-h]

Currently, to output some text, you have to remember to use a variable.

{% templ BasicTemplate() %}
  <div>{%= "Name" %}</div>
{% endtempl %}

I forget sometimes, and write this code:

{% templ BasicTemplate() %}
  <div>Name</div>
{% endtempl %}

And receive the error:

Generated code for 1 templates with 1 errors in 911.881µs
1 error occurred:
        * template.templ: template.templ parsing error: <div>: expected end tag not present or invalid tag contents at line 12, col 8 (index 178)

Improving the parser to parse HTML encoded text elements would complicate the code, but make a better developer experience, and lead to simpler templates.
