Update constant-keyword.asciidoc (#129053) (#129066)

Change the field name `date` to `@timestamp` so that users will be able to follow along with documentation. If not, then the date field is mapped as a keyword, which confuses users. (cherry picked from commit 73c56a5) Co-authored-by: Peter Titov <11168913+iamhowardtheduck@users.noreply.github.com>
