Revert "Update slf4j-api to 2.0.3"

[eed3si9n]

Ref sbt/sbt#7062

This reverts commit 8f594cf / #422

I don't think there's any reason for lm-coursier-shaded to bring in slf4j-api 2.x series, given that underlying Coursier is still on slf4j 1.x.

Maybe it would make sense to "pin" slf4j-ap to a 1.7. (or even a 1.) version range ?

In <YOUR_REPO>/.scala-steward.conf

updates.pin  = [ 
  { groupId = "org.slf4j", artifactId="slf4j-api", version = "1.7." } 
]

Good idea.
