ci: drop unused etherpad-lite checkout from test job

The test job checked out etherpad-lite and ran \`installDeps.sh\`
followed by an unused \`pnpm link --global\` solely as scaffolding.
cli-client itself has no tests beyond lint, and no runtime dep on a
locally-linked etherpad core. Drop the scaffolding so the job stops
inheriting etherpad-lite's lockfile/pnpm-config quirks (pnpm 11
\`autoInstallPeers\` mismatch).
