Downgrade spurious 'error' logs

[ctcjab]

Since it is expected that not all embeddings model providers will be loadable, it is wrong to log the case that one cannot be loaded with level 'error'.

Resolves #839.

Thank you for seconding my case! I think either info or warning is fine here, but I think I would lean towards warning and not showing this message at all when the provider is not allowed.

+1 to @krassowski , all changes can be made in get_em_providers() and I think this can be approved. (1) Change .info to .warning and (2) check if provider is not in blocked_providers before throwing the warning.

@ctcjab Thanks for opening a PR to fix this! Just one small comment below.

@krassowski @ctcjab Does there exist authoritative documentation on whether info or warning should be used in these logs? I don't have much experience with producing/consuming logs, so you two are the experts here.

Let's address this separately as this is a more complex topic, I opened #1120 to track this
