update changelog for edge-20.4.5 (#4314)

* update changelog for edge-20.4.5

This edge release includes several new CLI commands for use with
multi-cluster gateways, and adds liveness checks and metrics for
gateways. Additionally, it makes the proxy's gRPC error-handling
behavior more consistent with other implementations, and includes a fix
for a bug in the web UI.

* CLI
  * Added `linkerd cluster setup-remote` command for setting up a
    multi-cluster gateway
  * Added `linkerd cluster gateways` command to display stats for
    multi-cluster gateways
  * Changed `linkerd cluster export-service` to modify a provided YAML
    file and output it, rather than mutating the cluster
* Controller
  * Added liveness checks and Prometheus metrics for multi-cluster
    gateways
  * Changed the proxy injector to configure proxies to do destination
    lookups for IPs in the private IP range
* Web UI
  * Fixed errors when viewing resource detail pages
* Internal 
 * Created script and config to build a Linkerd CLI Chocolatey package
    for Windows users, which will be published with stable releases 
    (thanks to @drholmie!)
* Proxy
  * Changed the proxy to set a `grpc-status: UNAVAILABLE` trailer when a
    gRPC response stream is interrupted by a transport error
