Remove reference to component-config-tutorial in migration.md

[jordigilh]

This PR fixes a sanity lane failure in the documentation due to few errors when building the docs.

• Pin reference for component-config-tutorial to use v3 of the kubebuilder book documentation. This component is no longer supported by kubebuilder as per https://github.com/kubernetes-sigs/kubebuilder/discussions/3469 and removed in their docs in this PR.
• Updated link reference to kuttl to chainsaw as the site had moved the page elsewhere.
• Removed link to structured log in logging.md as the site is no longer available
