Update tutorials to reference 'Getting Started' as prereq

[david-martin]

Replaces #1126

Closes #1093

Other changes:

• Add Gateway creation to some tutorials where before it relied on a Gateway created by a make target
• Add some missing HTTPRoute sectionNames
• Remove make cleanup references
• Some small typos fixed

just because this will 404 on GH, maybe we include an absolute link? https://docs.kuadrant.io/latest/getting-started

(I realise this will 404 too right now until we do our next stable release)

Suggested change

	kubectl apply -f examples/toystore/toystore.yaml -n ${KUADRANT_DEVELOPER_NS}
	kubectl apply -f https://raw.githubusercontent.com/Kuadrant/kuadrant-operator/refs/heads/main/examples/toystore/toystore.yaml -n ${KUADRANT_DEVELOPER_NS}

maybe update with another absolute link for ease of use?
