Deprecation: #95009 - Passing TypoScript configuration as constructor argument to Exception handler
See forge#95009
Description
With 
        config. it's possible to
adjust the exception handler behavior of the frontend. It's even possible
to use an own exception handler class. Previously, the TypoScript configuration
was therefore passed to the exception handler via a constructor argument. This
has now been deprecated to allow the use of DI.
The configuration will now be passed using the new 
        set
method. This method will be enforced by the 
        Exception
in TYPO3 v12.
Impact
Using a custom exception handler, while not implementing the 
        set
method will trigger a deprecation log entry. The method will be enforced
in TYPO3 v12.
Affected Installations
All installations defining a custom exception handler via the TypoScript
configuration 
        config., while
not implementing the 
        set method.
Migration
Remove the 
        $configuration argument from the constructor of any
custom exception handler class and implement the 
        set
method instead.
