Clarify MinIO nonfunctional requirements

[DaveCTurner]

It is apparently nonobvious that if you run MinIO on poorly-configured
infrastructure then you're not going to get S3-like performance. This
commit spells out that the responsibility for the infrastructure
underneath MinIO lies with the user.

Thank you, the change looks good!

I've left a minor suggestion for style and clarity, in case you'd like to implement it.

Suggested change

[MinIO](https://minio.io) is an example of a storage system that provides an S3-compatible API. The `s3` repository type allows {{es}} to work with MinIO-backed repositories as well as repositories stored on AWS S3. Note however that the performance, reliability and durability of a MinIO-backed repository are dependent on the properties of the underlying infrastructure, as well as on the details of your MinIO configuration. You must design your storage infrastructure, and configure MinIO, so that your MinIO-backed repository has performance, reliability and durability characteristics which match AWS S3. If you need assistance with your MinIO configuration, please contact the MinIO support team. Other S3-compatible storage systems may also work with {{es}}, but these are not covered by the {{es}} test suite.

minor style suggestion to improve readability

@DaveCTurner , what if we include the entire MinIO paragraph in a highlighted note with three paragraphs inside?

Something like:

::::{admonition} MinIO considerations

Considering that the section is about compatible S3 services in general, but MinIO is actually the most important for us, I think highlighting this paragraph would be beneficial for the doc, and could look like:

Added a comment to change a bit the format of the paragraph, for your consideration.

I believe it's worthy to highlight the statements about MinIO in the doc, also considering that we have a doc that covers MinIO with ECE and refers to this section of the doc too.
