[ci skip] Revise TagHelper only permitting symbols doc.

Browse source 
Follow up to 454460e.

Rebuild the sentence so the bit about only symbols allowed comes less
out of left field and fits in better with the existing doc.

Also remove the `(Legacy syntax)` construct. The sections are properly
nested under `=== Options` with `====` and look fine on the generated
API doc site.
