Shared Canned Responses with images do not work for anyone other than the creator

Issue Summary

When an administrator creates a shared canned response that contains images, it won't work correctly for other users.

Steps to Reproduce

1. As a JSM administrator, create a shared Canned Response with text and images.
2. Using another JSM administrator or agent account, access a ticket and select the shared response.
3. Try to save the comment.

Expected Results

The comment is saved correctly.

Actual Results

It shows the following error:

We couldn't save your comment

It might be empty or have invalid formatting. If you copy-pasted, try removing the formatting and adding it directly in the editor.

On the network tab, it returned the following:

{
    "error": {
        "code": "JwtAuthoriser:AuthorisationError",
        "title": "The token does not allow requested operation. \"urn:filestore:collection:upload-user-collection--1659084799\" needs \"read\" permission",
        "href": "https://api.media.atlassian.com#UnauthorizedError"
    }
}

{"errorMessages":["ATTACHMENT_VALIDATION_ERROR"],"errors":{}}

The comment will work on tickets where the images already exist.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
