Add example for loading tar.gz or multiple tar files using `kind load image-archive`

[AnjaliMishra1st]

Summary

The documentation currently shows how to load a single image archive using:
kind load image-archive image.tar

It might be helpful to add a small note that users can run:
kind load image-archive --help

to see all available flags and options directly from the CLI.
This keeps the docs concise while still helping users discover additional usage details.

Proposed update

Add a short line under the existing example such as:

"For more options, see: kind load image-archive --help"

Notes

Happy to open a small PR for this if it sounds good.

I would like to work on this issue and open a PR once it is approved.

Hi, we appreciate the contributions, but please prefer short descriptions over large AI generated blobs. We have a lot of notifications to read through.

We don't currently show loading multiple archives at once because it is generally more efficient to create a single archive so image layers can be deduplicated, a single archive can have ~arbitrarily manage images.

Performance is somewhat tricky / workflow dependent but the easy answer purely from a performance perspective is generally to suggest the local registry approach.

On a certain level, the CLI is meant to be self-documenting through --help, we should avoid making the how-to guides in the docs super long.

Guidance on shell wildcard expansion (*.tar, *.tar.gz)

I don't think we should try to explain how to use shell features here, for example, because it isn't specific to kind and the docs pages have already gotten a bit unwieldy.

Maybe we should add some docs to explain the --help feature?

Thanks for the clarification! I understand your points.

Would it be helpful if I create a smaller documentation update that highlights the use of kind load image-archive --help instead?

Happy to follow the preferred direction.
