Remove Eigen3 minimum version requirement in CMake (ZEISS#163)

* Remove Eigen3 minimum version requirement in CMake

Previously, CMakeLists.txt required Eigen3 version 3.3 or higher.
Now, it will accept any available version of Eigen3 found.

* Add --skipApiVersionCheck flag to Azurite startup

Prevents API version compatibility issues by disabling version
checks when starting the Azurite blob service in CI. This helps
ensure tests run smoothly with newer client tools or SDKs.
