Update constant-keyword.asciidoc (elastic#129053)

iamhowardtheduck · iamhowardtheduck · commit 534398da84b7 · 2025-06-06T16:04:53.000+02:00
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)
