Upgrade to latest version of Kind

[Zanabazer]

Currently prombench and infra run using kind version 0.8.1 the latest version is v0.18.0. Version 0.8.1 of kind specifically causes an issue with linux kernel versions after 5.12.2 due to a change with the permissions regarding net/netfilter/nf_conntrack_max value.

Kind tries to set this value when launcing a cluster with the following command causing some of the events to fail.
infra kind resource apply -v CLUSTER_NAME:$CLUSTER_NAME -v DOMAIN_NAME:$DOMAIN_NAME
-v GRAFANA_ADMIN_PASSWORD:$GRAFANA_ADMIN_PASSWORD
-v OAUTH_TOKEN="$(printf $OAUTH_TOKEN | base64 -w 0)"
-v WH_SECRET="$(printf $WH_SECRET | base64 -w 0)"
-v GITHUB_ORG:$GITHUB_ORG -v GITHUB_REPO:$GITHUB_REPO
-v SERVICEACCOUNT_CLIENT_EMAIL:$SERVICEACCOUNT_CLIENT_EMAIL
-f ../prombench/manifests/cluster-infra

This issue has been addressed in kind version 0.11.1 and is documented here kubernetes-sigs/kind#2240.
