Correct file reference for ps-admin broken in tar.gz package

I am using ps-admin to enable rocksdb and it fails.

I use the following packages:

https://www.percona.com/downloads/Percona-Server-LATEST/Percona-Server-8.0.19-10/binary/tarball/Percona-Server-8.0.19-10-Linux.x86_64.ssl102.deb.tar.gz

The script is looking for ha_rocksdb.so in the following locations:

if [ ${ENABLE_ROCKSDB} = 1 ]; then
printf "Checking if RocksDB plugin is available for installation ...\n"
for ha_rocksdb_loc in "${SCRIPT_PWD%/*}/lib/mysql/plugin" "/usr/lib64/mysql/plugin" "/usr/lib/mysql/plugin"; do
if [ -r "${ha_rocksdb_loc}/ha_rocksdb.so" ]; then

But

the file is located in 

"${SCRIPT_PWD%/*}/lib/plugin/ha_rocksdb.so"
