Missing git client dependency

[rishiv5]

Describe the bug
Jenkins startup shows the following error when loading datadog plugin:

WARNING h.ExtensionFinder$GuiceFinder$SezpozModule#configure: Failed to load org.datadog.jenkins.plugins.datadog.listeners.DatadogSCMListener
java.lang.ClassNotFoundException: org.jenkinsci.plugins.gitclient.GitClient
...
Caused: java.lang.NoClassDefFoundError: org/jenkinsci/plugins/gitclient/GitClient

Looking into it further, I noticed that the datadog plugin imports the git-client plugin here but does not explicitly define a dependency in the pom.xml. Digging further into the dependency chain, it seems that the datadog plugin relied on an implicit dependency to git-client plugin through the pipeline-model-definition plugin. However, in their latest update, pipeline-model-definition no longer includes git-client as a dependency.

Proposal: Explicitly add git-client as a dependency of datadog plugin to ensure that git-client is loaded correctly during startup.

To Reproduce
Check Jenkins spin up logs or plugin list when installing the latest versions of datadog and pipeline-model-definition.

Expected behavior
Jenkins should contain the git-client plugin (via dependency resolution) if datadog plugin is installed.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment and Versions (please complete the following information):
Jenkins LTS 2.440.x
Pipeline: Declarative plugin (pipeline-model-definition) version after merge of jenkinsci/pipeline-model-definition-plugin#706
