PHP 8.2 Compatibility

[danielmorell]

With the release of PHP 8.2 there were a number of things that were deprecated. Fortunately, only one appears to impact the Rollbar PHP package. It is Deprecate dynamic properties.

We use dynamic properties to keep track of errors and exceptions that were explicitly passed to the Rollbar or "caught" by the handlers via the isUncaught property.

This can easily be fixed in both our error handler and fatal error handler since we use our own ErrorWrapper class, and we can just declare the property in it. For the exception handler we will need to think through how we handle it.

I wrote a test to validate this in commit 8d5fb81. The output on PHP 8.2 is as follows...

There was 1 failure:

1) Rollbar\Handlers\ExceptionHandlerTest::testDeprecatedDynamicProperties

This validates, the deprecation warning.
