docs(platform-stack): bump etcd-operator to v0.4.3

[lexfrei]

What this PR does

Bumps the pinned etcd-operator version in the v1.2 platform-stack guide from v0.4.2 to v0.4.3.

Accompanies cozystack/cozystack#2428, which re-vendors the chart and adds the backup.* API surface on the managed etcd app. The new backup parameters will land in content/en/docs/v1.2/operations/services/etcd.md automatically when the release-tag sync job pulls the updated packages/extra/etcd/README.md — no hand-edited doc is needed here.

Poem

🐰 A carrot, a hop, a version so neat,
From point-four-two to point-four-three we greet,
The etcd dances with lighter feet,
Small bumps make platforms complete! 🥕✨

Code Review

This pull request updates the etcd-operator version to v0.4.3 in the platform stack documentation. The review feedback suggests renaming the 'Operator' label to 'Kubernetes operator' to maintain consistency with other sections of the guide.

[gemini-code-assist]

For consistency with other sections in this document (such as ClickHouse, Kafka, and MariaDB), consider using the label Kubernetes operator instead of just Operator.
