Missing documentation on secrets, unable to publish to Minio about drone-s3

[moqmar]

Hm, thanks. I'm still getting the second first error with those two variable names somehow, so I assume it doesn't mean that it can't find the credentials but that there must be some other error...
EDIT: I fixed it - Minio was running behind Caddy, which wasn't configured as transparent, somehow causing the signature to fail. Leaving this open for the documentation issues, feel free to close it if you think it's not worth an issue. :)

I think although the variables "work the same way" as somewhere else, it's not really visible at any point in the documentation that they have that exact name, or even what secrets can be used with the plugin - the Docker plugin has a section titled "Secret References" for example, which is in my eyes missing for the S3 plugin.

I have never worked with the S3/Minio API before, so I have no idea what commonly used variable names are there, and I don't think a documentation should completely omit them even if they are commonly used.

The secrets should be aws_access_key_id and aws_secret_access_key which are pretty common variable names for AWS.

The documentation is missing the available secrets reference, but beside that the secrets are working the same way everywhere, so IMHO it's a waste of examples if every plugin got to list the usage of secrets.

That's why I have written The documentation is missing the available secrets reference...

The documentation should be clear enough in the meantime.
