Monolog and PHP 8 updates

[phil-nelson]

This update fixes an issue working with monolog 2.5 and above, where the IntrospectionProcessor added a callType field to its output. Since the ElasticCommonSchemaFormatter does not know about this field, it gets added as a top level key instead of within log.origin even when $useLogOriginFromContext is set. This can be demonstrated by simply checking out the main branch of this repo and running composer install && composer test.

This fixes the issue by adding callType to the list of known origin keys and also uses it (if available, so will still work with monolog < 2.5) within the log.origin.function field. E.g. MyClass::myFunction or MyClass->myFunction.

As a minor additional change it also marks compatibility with psr/log 2.x and 3.x.

These updates are required to be able to run tests with PHP 8.

Although still compatible with monolog < 2.5, ^2.5 is required for tests
