Add exlusion for logback-core to resolve CVE-2023-6378

[stephen-crawford]

Description

[Describe what this change achieves]
This change adds an exclusion for the transitive logback-core dependency that the Security plugin was still using as a test dependency.

This should resolve the flagging of CVE-2023-6378 even though we should not have been directly impacted.

The backport to 1.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/security/backport-1.x 1.x
# Navigate to the new working tree
pushd ../.worktrees/security/backport-1.x
# Create a new branch
git switch --create backport/backport-4049-to-1.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 babf0123383d8f8334c128071e75ec1334cc1725
# Push it to GitHub
git push --set-upstream origin backport/backport-4049-to-1.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/security/backport-1.x

Then, create a pull request where the base branch is 1.x and the compare/head branch is backport/backport-4049-to-1.x.
