Update hook_civicrm_caseSummary.md

Migrate Quickform Reference Documents

https://docs.civicrm.org/dev/en/latest/documentation/style-guide/#parts-chapters-sections

I was just trying this hook out in 4.7.22, the result pulls out the first element of the return and lists that on the case summary page. From the old docs, just gets the first key/val pair, then displays the first character of the label/value string.
