edge-22.6.2

This edge release bumps the minimum supported Kubernetes version from v1.20
to v1.21, introduces some new changes, and includes a few bug fixes. Most
notably, a bug has been fixed in the proxy's outbound load balancer that could
cause panics, especially when the balancer would process many service discovery
updates in a short period of time. This release also fixes a panic in the
proxy-injector, and introduces a change that will include HTTP probe ports in
the proxy's inbound ports configuration, to be used for policy discovery.
