Fixed Bad format specifier in XF\Error

[PaulB]

Affected version

2.2.1

Line 285 of src/XF/Error.php:

$args[] = sprintf('%.*G', $arg);

* isn't a valid precision value. In PHP 7.4.11, this is silently ignored, and the result is the string "G". In PHP 8.0 RC2, this results in an exception.

$ php7.4 -r 'printf("%.*G\n", 0.1 * 10);'
G

$ php8.0 -r 'printf("%.*G\n", 0.1 * 10);'
PHP Fatal error:  Uncaught ValueError: Precision must be an integer in Command line code:1
Stack trace:
#0 Command line code(1): printf()
#1 {main}
  thrown in Command line code on line 1
