FIX(localnet): Redirect babylond stderr to stdout

[vitsalis]

The babylond start command generates logs that are directed towards stderr leading to the tee command not capturing them.

A minor issue with this is that the logs are colored, meaning that depending on the editor that is used to view them, these might not be presented in a user-friendly format.

An alternative would be to output logs in JSON format using the --log_format json CLI argument, which would generate something like this:

...

Also, another thing to consider here is that given that the wrapper.sh script was retrieved from cosmos and osmosis has a similar script, maybe the stderr logs are not that useful to be captured.
