User CSV export does not treat usernames with comma properly

Summary

When exporting the user list to CSV, the importer won't handle it properly.

Example:

• Have a user with username = user,name;
• Export the users to CSV in the user management;
• Since there is a comma in the username, it will impact in the CSV row for that user, since the comma is the default delimiter:
  • Notice that the username will be divided in two columns. And because of that, all the other information will be wrongly positioned, even putting information in an additional column:
    

Environment

Jira Cloud

Steps to Reproduce

1. Have a user with comma in it's username;
2. Export the Users to CSV in the user management.

Expected Results

The username should not be divided. When there is a string with comma, it should be exported in quotes: "user,name".

Actual Results

The string is divided in two columns, impacting in the whole row for that user in the CSV
