XF\EmailBounce\Parser::getBounceTypeFromStatus does not handle statuses with multiple digits

[DragonByte Tech]

Affected version

2.3.7

Amazon SES will sometimes send a status such as 5.1.10, which will explicitly fail on this regex:

if (!$statusCode || !preg_match('#^\d\.\d\.\d$#', $statusCode))

Suggested fix:

if (!$statusCode || !preg_match('#^\d+\.\d+\.\d+$#', $statusCode))

Especially .edu email services have a tendency to use double digits, which is why bounce processing for .edu addresses often fails.
