chore(ci): enable overriding the runner in workflows (#4008)

olix0r · web-flow · commit b1f8fa54191d · 2025-07-17T17:22:42.000-07:00
We use the ubuntu-24.04 runner by default, but in forks this may not be appropriate. This change updates the runners to support overriding via the LINKERD2_PROXY_RUNNER variable.
