Review minio links and support in our docs

from https://github.com/elastic/docs-content/pull/3527

> References to "minio" may need a broader review of the docs, it looks like they moved the open source portion to the github repo: [@minio](https://github.com/minio)
>
> But also removed documentation updates from any hosted website:
>
> As of October 10, 2025, the MinIO object store documentation was pulled from web hosting.
>
> Moving forward, community users can build and host the documentation themselves using the instructions below.
>
> No further development of the documentation is planned at this time. The project maintainers will make best efforts to review and merge PRs from the community.
>
> I update the links we had for ECE to point to the github repo mainly, but we may want to re-work this whole page, especially if we can't reliably link to documentation.

## action

audit minio link context (using the PR for reference) and see if the page is still usable
