patching bash prompt in c9s no longer necessary since 2025?

[shalberd]

Getting the following error while building a new base image with this command run under directory /base:

make all RELEASE=2025a DATE=20250110

[1/2] STEP 18/20: RUN patch -u /opt/app-root/bin/activate -i patch.txt &&     rm patch.txt

Error: building at STEP "RUN patch -u /opt/app-root/bin/activate -i patch.txt &&     rm patch.txt": while running runtime: exit status 1

make: *** [c9s-py39] Error 1

Is is possible that the latest CentOS9 from sclorg
quay.io/sclorg/python-311-c9s:c9s
does not require that patch anymore?
