Correct isthmus-cli SLF4J dependency

- Remove concrete slf4j-jdk14 provider dependency from isthmus.
- Add concrete slf4j-jdk14 provider dependency to isthmus-cli.

Library components should only depend on slf4j-api, allowing consumers
to select an appropriate concrete logging provider implementation. Being
a self-contained (CLI) application, isthmus-cli can depend on a specific
SLF4J provider.
