The issue is that no wheels are available for scikit-image for Python 3.11
Python libraries can have code that is not written in Python (like C, C++, FORTRAN, Rust, ...) and in order to use those, you need to compile that code for your version of Python, your OS and CPU architecture.
Fortunately, Python offers a packaging mechanism known as wheel to provide that precompiled code. Package maintainers can generate those wheels to avoid the end user having to compile it from sources.
In your case, as Python 3.11 just got out (beginning of the week), the maintainers of scikit-image
didn't have the time to package the wheel and pip tries to install it from sources (hence the message asking you to install Microsoft Visual C++ 14).
