docs: pipeline: inputs: kubernetes-events: document kube_watch_timeout

[eschabell]

Document the new kube_watch_timeout parameter, which bounds the lifetime of a Kubernetes watch request through the timeoutSeconds API parameter and applies a matching read idle timeout on the HTTP client. Explain that reconnection resumes from the last recorded resource version and that 0 disables both timeouts.

Note, change for code merge without corresponding docs PR.

Summary by CodeRabbit

• New Features

  • Added the kube_watch_timeout configuration option to limit Kubernetes watch request and idle connection durations.
  • Setting the value to 0 preserves indefinite connections.
  • Reconnections resume from the last recorded resource version.

• Documentation

  • Documented the new configuration option and its behavior.

Warning

Review limit reached

@eschabell, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 32 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
