Readding slf4j-bridge

[vigoo]

This PR readds the slf4j-bridge subproject, which enables users to use a lightweight, ZIO based logger (such as the console logger) without including any Java logging frameworks, but still capture the 3rd party library logs via SLF4j.

Can you run Scalafix and Scalafmt?

We should have an official test logger backend that captures the log entries

👍 Yes. Possibly this should be bundled into ZIO Test so you can automatically access logs from your tests.

It feels a bit unusual to not be able to log a message together with a throwable, although I worked around that by wrapping the failure in one more exception that encapsulates the custom message

See discussion on Slack.

I'm not sure how setting up the whole thing will look like in the real world, so maybe having the bridge initialization as a ZIOApp is not a good idea.

I think it should be a RuntimeConfigAspect, instead. What do you think about that?
