feat: add contributing.yaml for update cli

[saurabhraghuvanshii]

close #906

Add updateCli to keep contributing.md up to date .

That is a good job, thanks!

I've added a few suggestion, some are nit picking, other are blocking. Mainly, I would suggest to keep the same documentation block with prerequisites updated.

The addition of many details makes the change hard to maintain for us:

• URL are fragile and could break quite often
• The amount of PRs opened by the manifest in its current state will be quite high for a low value (JDK and maven version are HIGH value, but knowing the current version of the agent, which changes 1 or 2 a week is low value)

I guess it underlines that the Jenkins infrastructure is missing a real "documentation" webstie with permalink and details

in order to have a fully functionnal updatecli, we need :

• to provide a value file (see https://github.com/jenkins-infra/helm-charts/blob/main/updatecli/values.yaml)
  this step will allow a manuel check of the manifest with updatecli diff --values ./updatecli/values.yaml --config ./updatecli/weekly.d/contributing.yaml
• to setup a dedicated jenkinsfile jenkinsfile_updatecli (see https://github.com/jenkins-infra/helm-charts/blob/main/Jenkinsfile_updatecli)
• to set up infra.ci to manage it as code (see https://github.com/jenkins-infra/kubernetes-management/blob/0d4ffc76660c8cb667a9f7fb3f9f8b94a7fc7bf7/config/jenkins-jobs_infra.ci.jenkins.io.yaml#L173-L318)
