Sergii Golubev 0fb81d6643 Docs: Update id-field.asciidoc
It is strange to provide an example with `"store" : false` when talking about possibility of enabling the field to be stored.
Broke the line in the mapping in two lines for better readability.
More verbose sentence above the mapping.

Closes #7894
