Update envoy and go-control-plane and fix deprecations

[ukclivecox]

This PR updates envoy and go-control plane and fixes configuration (and issues) that were present in reverted PR #4867

• Updates envoy to v1.26.1
  • Fix listener filter creation by specifying the type as dscussed here and here due to a change from 1.22
• Updates go-control-plane to 0.11.1 (just released)
• fixes deprecations in resources
  • Use DefaultSourceCode rather than inlineCode for LUA script
  • Use StringMatcher rather than older methods in header matching
  • Removes TotalWeight as its no longer needed in weighted clusters

Note: 0.11.0 of go-control-plane causes issues in which the delta XDS updates seem to go into a loop showing

This seems to be fixed in 0.11.1 (released today!) but its unclear why from release notes and slack disucssion with Alex Holmes (go-control-plane lead).

Envoy tested via running through notebooks locally and on k8s.
