"alt-text.org" doesn't exist, use "www.alt-text.org" in footer instead

Describe the bug
The link to alt-text.org in the page footer does not work because there are no IP addresses associated with the domain name.

However, www.alt-text.org (note additional "www." in front) works.

To Reproduce
Steps to reproduce the behavior:

1. Go to my.alt-text.org
2. Click on '...' aka the menu button
3. Click on the A+eye logo
4. A new browser tab opens, but the page, https://alt-text.org, cannot be loaded.

Expected behavior
The link behind the logo opens correctly.

Desktop :

• OS: Linux
• Browser: Firefox
• Version 121.0 64-bit

Additional context
I have provided a Pull Request for a workaround which changes the link to the "www." version. See #41.

I forgot to say: An alternative solution to the problem would be to set up appropriate DNS entries for alt-text.org, and possibly adapt the webserver config to show the same contents or forward to www.alt-text.org
