AutoMarkFolderRead v1.5.3

Added "Dark Mode" support for the options panel.

If you experience issues with the "dark mode" implementation for the options panel please let me know here.
Thank you.

Note:
If you are using Thunderbird until version 121 then use the latest v1.5.* release of the add-on.

For Thunderbird 122 and above use the add-on version 1.6 or later.
