[Github] Install sccache from apt repo in CI container

[boomanaiden154]

This patch installs sccache using apt-get in the CI container build process rather than manually downloading it from github releases. This makes things quite a bit simpler and means we are not manually handling things like hash/signature verification. This is only possible now that we are using ubuntu 24.04 by default.
