JIRA: Add notify_users option to 2 methods (#1278)

* Add notify_users option to 2 methods

update_issue_field method can utilize "notifyUsers" query parameter to enable/disable email notification.
https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-put

So does issue_edit_coment method as well.

* Update JIRA docs
