use python shipped with Squish

[saw-jan]

Currently, we are building the specific python version and using it for Squish tests. Squish comes with python3 which we can utilize.

Open tasks:

• remove python build commands
  

  squish/fedora/Dockerfile.amd64

  Lines 89 to 96 in 16cad0f

  	RUN curl https://dl.fedoraproject.org/pub/fedora/linux/releases/39/Everything/x86_64/os/Packages/p/python3.10-3.10.13-1.fc39.x86_64.rpm \
  	-so python3.10.13.rpm && \
  	dnf install -y ./python3.10.13.rpm python3.10-devel && \
  	dnf autoremove -y && \
  	dnf clean all && \
  	dnf clean dbcache && \
  	rm ./python3.10.13.rpm && \
  	python3.10 -m ensurepip

• make squish python available globally

Notice: In the build stage, we still need to install python so that command should not be touched
