Fix phpcs pipeline

Changes looks good ~~ marking this one RTBC

@wells gitlab CI having default branch 11.x so next major won't work and same goes for upgrade_status. Only thing we can keep is previous_major with minimum php version 8.3
Below variables will work on D10.x

OPT_IN_TEST_PREVIOUS_MAJOR=1
CORE_PREVIOUS_PHP_MIN: 8.3

@ankitv18 so is there anything need to change or add?
