docs: add NetBird client compatibility to the operator support matrix

[emrcbrn]

What

Adds a NetBird client compatibility section to the Kubernetes Operator Support Matrix, making explicit which NetBird client each operator release is tested and supported with.

Why

The page covered Kubernetes and control-plane compatibility, but not the NetBird client. Each operator release is built and tested against a specific NetBird release and ships that exact client, so users had no documented way to know which pairing is supported.

Details

• States the current supported pairing: operator v0.8.0 with NetBird v0.72.4.
• Adds a table of the tested client per recent operator release (v0.4.0 through v0.8.0).
• Notes that each release pins the client image by digest, so a default install already runs the supported combination, and that overriding routingClientImage is neither supported nor tested.
• Versions were taken from each release's pinned client image (and cross-checked against go.mod) in the operator repo.

Also replaces an em dash in the Kubernetes compatibility section with two plain sentences.

📝 Walkthrough

Walkthrough

The Kubernetes operator support matrix now documents tested NetBird client versions, default client images, digest pinning, and unsupported image overrides. It also rewords one Kubernetes compatibility sentence.

Changes

Kubernetes operator compatibility

Layer / File(s)	Summary
Document operator and client compatibility src/pages/help/support-matrix/kubernetes-operator.mdx	The page adds a NetBird client compatibility table and documents tested releases, default images, digest pinning, and unsupported routingClientImage overrides. It also removes an em dash from an existing paragraph.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to c69c3

The documentation now defines supported operator and NetBird client pairings, but issue reports do not yet request the client version and effective image override, which may make troubleshooting unsupported combinations less reliable. The PR is otherwise mergeable with owner awareness or a follow-up documentation update.

Poem

A rabbit reviews the client chart,
With tidy versions lined in art.
Digests guard each image tight,
Helm overrides stay out of sight.
The operator hops through every part.
