    Fix string formatting of version number
    
    According to Lua 5.3 manual %q is for formatting strings and escaping
    them so that they can be read again by Lua. This particular number is
    however floating point and %q chooses to format it like with %a, that
    means hexadecimal. This greatly reduces the the readability. Because
    ConTeXt's OpenType loader versions are always in the format `x.yyy` we
    can use %.3f directly.
    
    This is the difference in output:
    ```
    luaotfload | init : Context OpenType loader version 0x1.8e76c8b439581p+1
    luaotfload | init : Context OpenType loader version 3.113
    ```
    
    There may be other places where this issue may be relevant, but this
    line is printed to every log file.
