Set logback dependency to 1.2.x

[sbesson]

Bio-Formats 6.12.x which is a transitive dependency of this component ships slf4-api 1.7.x which is only supported up to 1.2.x While using logback 1.3.x is doable and Gradle will automatically select a higher version of slj4-api 2.x, this might cause problems for downstream components using different resolution mechanisms like Ivy or Maven

Hopefully this is the solution for the build failures of https://github.com/ome/openmicroscopy/pull/6341

Assuming no side-effect on the rest of the CI, is the plan to get this merged and released as 5.6.2 to fix the downstream build?

Two failures in the CI builds using 6c02c0e:

• the first one came from the interplay between this PR and https://github.com/ome/ome-common-java/pull/73 https://github.com/ome/bioformats/pull/3956 https://github.com/ome/bio-formats-examples/pull/105 which are bumping the slf4j-api to 2.x which is incompatible with logback 1.2.x. The three PRs have been switched to draft mode and excluded from the CI merge queue. Once this is merged and when these PRs get reincluded, we will need a companion PR re-bumping the logback version to 1.3.x in this repository
• the second one was an Ivy error while retrieving org.slf4j#slf4j-api;1.7.32!slf4j-api.jar https://merge-ci.openmicroscopy.org/jenkins/job/OMERO-build/1493/console. The issue is fairly similar to the original error in https://github.com/ome/openmicroscopy/pull/6341 which motivated this PR and fundamentally comes from known issues associated with transitive dependencies resolution across different build systems with different conflict management policies. Solving the issue properly goes beyond the scope of this PR. For the time-being, 3b2a2e3 proposes to re-use a strategy used previously in similar situation and pin the slf4j-api dependency to the same version declared in Bio-Formats.
