## Description

### Steps to reproduce

1.  In `Nextcloud`, setup `integration_openproject` with `OAuth`.

2.  Connect the `Nextcloud` admin with an `OpenProject` admin.

3.  In `OpenProject`, navigate to  `Project settings > Files` of the `Demo Project` and add a file storage of type `Nextcloud`.

4.  In `Nextcloud`, select a file and navigate to sidebar `OpenProject` tab.

5.  Search for any of the work packages in the `Demo Project` and observe the avatar of the `OpenProject` admin.

6.  In `OpenProject`, navigate to `Account Settings -> Avatar` and change the avatar.

7.  In `Nextcloud`, refresh the page and observe the avatar of the `OpenProject` admin displayed in the `OpenProject` sidebar.

### What is the buggy behavior?

  - The old avatar continues to be displayed because the avatar endpoint response is cached by the `browser` for `24 hours`.
    
    Request:
    
    ``` bash
    GET https://nextcloud.local/ocs/v2.php/apps/integration_openproject/api/v1/avatar?userId=4&userName=OpenProject%20Admin
    ```
    
    Status Code:
    
    ``` bash
    200 OK (from disk cache)
    ```
    
    Cache header:
    
    ``` bash
    Cache-Control: private, max-age=86400, must-revalidate
    ```
    
    The `max-age=86400` header causes the browser to cache the avatar response for `24 hours`.
    
    If `Disable cache` is `enabled` in `DevTools` and the page is refreshed, the request is fetched again from the server:
    
    Request:
    
    ``` bash
    GET https://nextcloud.local/ocs/v2.php/apps/integration_openproject/api/v1/avatar?userId=4&userName=OpenProject%20Admin
    ```
    
    Status Code:
    
    ``` bash
    200 OK
    ```
    
    The updated avatar is then displayed correctly.

### What is the expected behavior?

  - Updated OpenProject avatars should be reflected in Nextcloud without requiring users to clear or disable their browser cache.
