[Bug] rm: /tmp/web5-x86_64-apple-darwin

When attempting to install Web5 CLI, the last line of the script prints an error message. Seems this is because this file was already moved in a previous step. So, I think it's safe to just remove the cleanup step in install.sh

Actually going to close this and make this a new issue with more details, so Hacktoberfest participants can fix tis. Maybe with a title like Fix broken installation script for Web5 CLI. I wanted to edit the issue, but I'm unable to.
