Monolog handler fails when the extra data has numeric array keys

[pontus-mp]

If $key is an integer in the following line, the function call will fail with Uncaught TypeError: Argument 1 passed to Sentry\State\Scope::setExtra() must be of the type string, integer given.

sentry-php/src/Monolog/Handler.php

Line 62 in 50f5893

$scope->setExtra($key, $value);

I suggest adding a cast to string there, or possibly making the first argument to setExtra more relaxed.

Good catch! I don't have an example in mind of why the $key should not be a string, so I would say that casting is the best solution here. Are you willing to open a PR to fix it?

Sure, done!
