Non-descriptive error logging for too long memo

[ertemann]

The following error is issued by hermes version v1.10.3 after trying to start the process with a config that has a memo for any chain longer than 50 characters.

The Hermes configuration file at path '/home/deploy/.hermes/config.toml' is invalid, reason: parse error: invalid CosmosSdk config: invalid length 52, expected a string length of at most 50 for key `chains` at line 128 column 1 Please see the example configuration for detailed information about the supported configuration options: https://github.com/informalsystems/hermes/blob/master/config.toml

This error however seems to indicate that too many chains are configured which is not at all the case.

-- proposed solution better describe the actual problem with the config
