Explicitly Set Fixed UID/GID for ClickHouse User in Server Images

Official CH changelog text
Explicitly set uid / gid of clickhouse user & group to the fixed values (101) in clickhouse-server images. #19096 (filimonov).
ClickHouse server Docker images now explicitly set the user and group IDs for the clickhouse user and group to fixed values (101).

Why it matters

This change ensures consistent UID and GID values for the clickhouse user and group across Docker images, improving permission management and avoiding conflicts with host system user IDs when mounting volumes.

How to use it

Users simply run the updated clickhouse-server Docker images where the clickhouse user and group have fixed UID and GID set to 101. No additional configuration is required.
