[fix][build] fix permission denied error while running install-pulsar-client.sh

[nullscript]

Fixes #18443

Motivation

I tried to build docker image on my win10, and I use wsl2 for my docker, all my softwares versions are listed on #18443. I have encountered "permission denied" error while running install-pulsar-client.sh, seems it happens on some linux kernel. I searched this error on stackoverflow and I got this, https://stackoverflow.com/questions/69323982/permission-denied-in-docker-entrypoint. So I add RUN chmod +x /pulsar/bin/install-pulsar-client.sh, and it works fine for me.

Adding this may happen many beginner reduce this kind of problems.

Modifications

Add chmod +x command to dockerfile

Although the original script works well on macOS for me.
