OC-26097: kpi-docker-eks (form-designer) Jenkins Job is failing to build KPI image

- As KPI Dockerfile is using python base image with version 3.10. It always pull the latest patch version of python 3.10. The last successfull kpi build was with python version 3.10.18. After python:3.10 image gets updated with python version 3.10.19 (see: PR docker-library/python#1088) , kpi build starts failing. Thus explicity adding python version 3.10.18 to make build successfull.
