Description of problem

NE-1951 taught the 4.18 ingress operator about an ack-4.18-gateway-api-management-in-4.19 admin ack. The message for that ack links a release-note section. OSDOCS-5036 added that release note, linking to the Preparing for Gateway API management succession by the Ingress Operator section. However, the link anchor is currently:

$ curl -s https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html/release_notes/ocp-4-19-release-notes | grep -o '"[^"]*#[^"]*manage[^"]*succession[^"]"'
"https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html-single/updating_clusters/#nw-ingress-gateway-api-manage-succession\"

which doesn't quite match the actual anchors on the target page:

$ curl -sL https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html-single/updating_clusters/ | grep -o ' id="[^"]*manage[^"]*succession[^"]*"' | uniq
 id="nw-ingress-gateway-api-manage-succession_updating-cluster-prepare"

And even then, the target section doesn't wrap up with details on how to apply the ack once the admin is ready to do so:

$ git grep ack-4.18-gateway-api-management-in-4.19 origin/enterprise-4.19 -- | wc -l
0

Version-Release number of selected component

4.19 docs linked from the 4.18 ingress operator.

How reproducible

Every time.

Steps to Reproduce

1. Start from https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html/release_notes/ocp-4-19-release-notes#ocp-4-19-networking-gateway-api-crd-lifecycle_release-notes
2. Get walked through how to understand the shift in Gateway API CRD management.

Actual results

Broken anchor makes Gateway API CRD management section harder to find, and nothing in that section explains how to apply the ack-4.18-gateway-api-management-in-4.19 when you're ready.

Expected results

Docs are easy to follow, and explain how to apply the ack-4.18-gateway-api-management-in-4.19 ack when you're ready.

Additional info

See here for example docs around applying a different admin ack, in case that's helpful for pattern-matching.
