(PE-38404) Install script for AL2

[amitkarsale]

AL2 uses yum commands by default compared to dnf which is replaced in AL2023.

Tested this on a amazon-7-arm64 VM to install the latest 7.31.0 agent and it worked:

Looks good to me, re-tested this install.sh with a few different EL platforms including amzn2 and works.
