[TASK] Add phpunit 11.2.0 as conflict version due to regression

PHPUnit refactored the double creation to support doubling
readonly classes [1], thus breaking classes where the class
constructor is called with constructor arguments, but calling
itself a class method which is mocked using the `onlyMethods()`
setup option. This leads now to some internal state setup issue
and is reported as `regression` [2] providing steps to reproduce
it.

This change adds `phpunit 11.2.0` as conflict to the monorepo
version to avoid using it in nightly tests for now, until a
proper regression fix has been implemented in phpunit.

Used command(s):

  \
    cat \
    <<< $(jq --indent 1 --tab \
      '."conflict" += {"phpunit/phpunit": "11.2.0"}' \
      composer.json) > composer.json \
    && Build/Scripts/runTests.sh -s composer -- update --lock
