Remove uid_entrypoint.sh symlink from Dockerfile #24270
Description
Summary
Remove the uid_entrypoint.sh -> entrypoint.sh symlink from the Dockerfile.
The symlink was added in PR #7047 as a temporary backward-compat measure after renaming.
Motivation
Reduce ambiguity between entrypoint.sh vs uid_entrypoint.sh.
Proposal
Remove the symlink creation line from the Dockerfile:
# keep uid_entrypoint.sh for backward compatibility
RUN ln -s /usr/local/bin/entrypoint.sh /usr/local/bin/uid_entrypoint.sh
