Adding a string with the key `user` to loging context throws an exception

[przemyslaw-przylucki]

Environment

Sentry: 3.1.3
Laravel: 9.43.0

Steps to Reproduce

1. Use sentry as the logger driver

        'stack' => [
            'driver' => 'stack',
            'channels' => ['daily', 'sentry'],
            'ignore_exceptions' => false,
        ],

2. Send a log

logger()->info('user', ['userId' => 5, 'user' => 'abc'])

Expected Result

The log is added without any problems.

If this is expected behaviour, this should be explicitly documented somewhere

Actual Result

An exception is thrown, b/c user is apparently a reserved keyword, and passing it in the log creates an exception

@stayallive WDYT?

• Ignore none arrays here and check that keys in the user context are strings https://github.com/getsentry/sentry-laravel/blob/6af4ae521ac4acd06a1bfc100ae1880b2cef1ba5/src/Sentry/Laravel/SentryHandler.php#LL197C58-L197C58
• Cast to string here https://github.com/getsentry/sentry-php/blob/d6671685ce13fdaf70113c7ba2ad1a2a31373fec/src/UserDataBag.php#L110. But this feels meeh.
