Webhook data shows a wrong updated time

Issue Summary

Webhook data shows a wrong updated time

This is reproducible on Data Center: yes

Steps to Reproduce

1. Install Jira Server/Data Center v8.20.10
2. Create a Software or Service Management project and an issue
3. Create a webhook to trigger as 'Issue Created' and 'Issue Updated' events ('attachment1').
4. Add a comment to the issue and keep adding a few comments with a gap in time.
5. Analyse the data received at the destination and check for updated time under 'assignee' element.

Expected Results

The updated time under assignee element shows latest update time.

               "assignee": null,
                "updated": "2022-09-01T16:08:01.216+1000",

Actual Results

The updated time under assignee element shows the previous update time. Other events like when the issue is changed status or changed assignee etc., the updated time under assignee element shows latest update time. Only adding a comment takes the previous time (the first comment takes the time of previous issue update like issue assignment).
