[REM] crm: remove unnecessary mail template data

This template was linked to an old automated rule used as a demo sending
an email to old opportunities. The demo automated rule has been removed
since. Moreover there is already a mail template used for mass mailing
in crm. No need to have unnecessary data especially it is not linked to
any business flow.

This commit is linked to task ID 1841503 (and 1868112) and to PR #25388
(and #25889).
