Missing "controller-tools" Version Upgrade Instructions in the v1.25.0 Migration Guide

[tiwalter]

The v.1.25.0 migration guide does not contain any instructions regarding the controller-tools version update to v0.10.0.

The version update was made here: https://github.com/operator-framework/operator-sdk/blame/v1.25.0/testdata/go/v3/memcached-operator/Makefile#L186 within this PR (#6047)

We need to add the follwing instruction:
In the Makefile file, replace CONTROLLER_TOOLS_VERSION ?= v0.9.2 with CONTROLLER_TOOLS_VERSION ?= v0.10.0
