Details:
uptime and diff are both required by the build process that we use. diff is needed by the openjdk configure step, and uptime is currently used in linux.sh and https://github.com/adoptium/temurin-build/blob/d1c15a677275e44c3fed8c287159743794e88f6a/sbin/prepareWorkspace.sh#L428 (The former could likely be removed though, and the the latter was for diagnostic purposes, but potential still useful when debugging performance issues.

uptime is still in CentOS 8, but not in CentOS Stream 9+'s base docker images. diff was in 7 but is not in 8 and above. Both of these distributions will need procps-ng and diffutils added to their list of required packages in the playbooks. Note that while earlier versions already have these, we shouldn't add procps-ng to them all as CentOS6/RHEL6 uses the earlier procps instead.
