[ResponseOps][Cases] Remove deprecated date format from telemetry (#2…

…00331)

## Summary

The Cases telemetry uses a deprecated date format that will not be
supported in 9.0. This PR changes the format of the date set in the
`format` field as suggested here
https://www.elastic.co/blog/locale-changes-elasticsearch-8-16-jdk-23.
Specifically, it changes `Y` to `y`. From the docs:

> In particular, if you are using the Y specifier as part of a calendar
date format, you are probably using it erroneously; Joda time uses Y to
represent year-of-era, but the JDK uses Y to represent week-years. You
need to modify your format to use y instead, or change to a built-in
format.

Fixes: elastic/kibana-team#1188
