133530: roachprod: add `google_compute_engine` to `DefaultPubKeyNames` r=vidit-bhat,herkolategan,stevendanna a=srosenberg

roachprod uses `DefaultPubKeyNames` to look for a public SSH key under $HOME/.ssh. Historically, folks would create an SSH keypair named `google_compute_engine`, so we add it to the list of default keys to scan.

Epic: none

Release note: None
