Please document the usage of @text

I had to dig through the source code for this syntax that does exactly what I want, it should really be documented in the README.

Example usage:

# Parse out all the text of the Git glossary terms
curl -s https://git-scm.com/docs/gitglossary \
    | hq '{ headings: dt.hdlist1 | [{ text: @text }] }' \
    | jq --raw-output '.headings[].text'

Good shout! I'll add it!
