Issue:
Upgrade Micrometer to latest release
The version of Micrometer currently building with this project is old and doesn't contain the new tracing/observation APIs. If we upgrade to 1.10.3 (or later) there shouldn't be any problems for the build or for existing users because existing APIs are unchanged, and it will clear a path to supporting Spring Boot 3 properly.

Pull request description:
Bump micrometer version to latest
Fixes #828
