Backport #23768 (no source code conflict, only some unrelated
docs/test-ini conflicts)

Some storages like:

 * https://developers.cloudflare.com/r2/api/s3/api/
 * https://www.backblaze.com/b2/docs/s3_compatible_api.html

They do not support "x-amz-checksum-algorithm" header

But minio recently uses that header with CRC32C by default. So we have
to tell minio to use legacy MD5 checksum.

Backport #23166

Allows using Minio with untrusted certificates

Closes #23128

Unfortunately there was a mistake in #13164 which fails to handle
os.PathError wrapping an os.ErrNotExist

* The `.Use` of storageHandler before setting up the template renderer
causes a panic if there is an error to log.
* The error passed to `ctx.Error` in that case may contain sensitive
information and should not be rendered to the end user. We should
instead log the error and render a simple error message.
* There is no handling of missing avatars and this needs a 404. Minio
errors need to be mapped to standard golang errors such as
os.ErrNotExist.
* There is no logging when storage is set up.
