wasme deploy fails when serverHeaderTransformation exists in gateway config

[jameshbarton]

Describe the bug
wasme deploy fails when serverHeaderTransformation already exists in gateway config. For context, see this blog post.

To Reproduce
Steps to reproduce the behavior:

1. Install httpbin:
   kubectl apply -f https://raw.githubusercontent.com/istio/istio/master/samples/httpbin/httpbin.yaml
2. Add a route to httpbin:

apiVersion: gateway.solo.io/v1
kind: VirtualService
metadata:
  name: httpbin
  namespace: gloo-system
spec:
  virtualHost:
    domains:
    - '*'
    routes:
    - matchers:
      - prefix: /
      routeAction:
        single:
          upstream:
            name: default-httpbin-8000
            namespace: gloo-system

3. Patch the gateway to add serverHeaderTransformation:

kubectl patch gateway -n gloo-system gateway-proxy --type merge -p '{"spec":{"httpGateway":{"options":{"httpConnectionManagerSettings":{"serverHeaderTransformation":"PASS_THROUGH"}}}}}'

4. Deploy a WASM filter to the gateway. Observe the unexpected error. Running this without the patched gateway from step 3 works fine.

% wasme deploy gloo webassemblyhub.io/jameshbarton/remove-headers:v1.0 --id=remove-headers --config "x-envoy,server"
Error: All attempts fail:
#1: converting output crd: reading crd spec on resource gateway-proxy in namespace gloo-system into v1Gateway: unknown field "serverHeaderTransformation" in hcm.HttpConnectionManagerSettings

Expected behavior
The wasme deploy succeeds with no errors.

We'll need to bump the version of Gloo used to one that includes this field - https://github.com/solo-io/wasm/blob/master/tools/wasme/cli/go.mod#L30 (We are using Gloo 1.5 and I believe this field was added in Gloo 1.6)
