docs(va): filter shot with rows to see, and no wrapperless crop

Captured from the report viewer at 1920x1100: two prompts (a value list and a
date), 21 rows returned by
FILTER : ( ( SOME_DROPDOWN = 'Option 1' AND SOME_DATE = '01JUL1960'd ) ).

- drops the header/FILTER crop, which had no VA chrome, and the sentence it
  illustrated
- drops the "single row it matches" wording, which no longer describes the
  picture
- documents the date clause as a code block instead of a second image
