chore: kubernetes contexts extension v0.1.0

[feloy]

New Kubernetes contexts extension.

@vancura @MariaLeonova we probably want a specific logo for this extension, I have included a Kubernetes logo for the moment. There is this one I have created on my side, which may be a starting point: https://github.com/podman-desktop/extension-kubernetes-contexts/blob/main/packages/extension/icon.png

In `@static/api/extensions.json`:
- Line 2237: The "lastUpdated" metadata entry currently set to the future
timestamp "2026-03-02T08:00:00Z" should be changed to the actual publish/update
time (e.g., the PR creation timestamp or the real release time); locate the JSON
object containing the "lastUpdated" key in the extensions metadata and replace
that future-dated value with the correct ISO 8601 timestamp so registry
ordering/recency is not misleading.

In `@static/api/extensions/podman-desktop/kubernetes-contexts/0.1.0/README.md`:
- Line 5: Update the user-facing README sentence that currently reads
"Kubernetes Contexts is an open source extension for Podman Desktop to manage
Kubernetes contexts." to use a hyphenated compound adjective: change "open
source extension" to "open-source extension" so the sentence reads "Kubernetes
Contexts is an open-source extension for Podman Desktop to manage Kubernetes
contexts."
- Around line 41-49: The fenced code block in README.md is missing a language
label (MD040); update the opening triple-backtick in the snippet that starts
with "$ git clone
git@github.com:podman-desktop/extension-kubernetes-contexts.git" to include
"bash" (i.e., change "```" to "```bash") so the block is explicitly marked as
shell/bash for markdown linting and proper syntax highlighting.

@feloy ok! Can you please specify all the places that it will be used?
I am assuming in the left nav bar on installation, in the extensions catalog,.. anywhere else?
