I would like to close this with this script. @matyasselmeci Want to review?

Repo: https://github.com/PelicanPlatform/get-pelican
Script: https://github.com/PelicanPlatform/get-pelican/blob/main/get_pelican.sh

I have written test for ubuntu, debian, alpine, macos and centos-stream

I made some tweaks to the script in PelicanPlatform/get-pelican#1 ; I also created an issue for generic Linux support at PelicanPlatform/get-pelican#2 .
