CAPI: Request observability-bundle >= 1.7.0.

This PR update the releases requests to make sure we upgrade observability-bundle to v1.7.0 in newer releases

[Gacko]

We cannot introduce this in CAPV v28.0.1 nor v29.0.0. There should not be any app changes for < v29.0.0 and CAPV v29.0.0 itself should first get into alignment with what we currently have in the latest releases of other providers.

So for CAPV, we could integrate observability-bundle v1.7.0 in CAPV v29.1.0 earliest.

I already talked to Nick about this and we agreed on first getting to a point where all CAPI providers use the same app versions + latest patches of Flatcar, Kubernetes and OS Tooling. This means we'll probably also forge a CAPA v29.3.1 and CAPZ v29.2.1.

Since CAPA v29.3.1 and CAPZ v29.2.1 would match the semver comparison you're introducing here and we do not ship minor app bumps in patch releases, I'd ask you to first request observability-bundle v1.7.0 for CAPA v29.4.0, CAPZ v29.3.0 and CAPV v29.1.0 by using >= 29.4.0, >= 29.3.0 and >= 29.1.0 as with > 29.3.0, > 29.2.0 and > 29.0.0 you would also request it for patch releases.

Alright I updated the requirements accordingly
