Increase privilege of `github-bot` on Jenkins

[mmarchini]

I just added github-bot credentials to nodejs/reliability so that we can generate daily reports of failures in the CI via GitHub Actions. Unfortunately, it seems like the bot doens't have enough permissions on Jenkins, which leads to ncu-ci failing:

I tried to run the same command (ncu-ci walk pr --stats=true --markdown $PWD/results.md) on my machine with my credentials and with bot credentials. The command works with my credentials and it fails with bot credentials. Not sure which permissions it needs in order to make the required API requests to Jenkins. Also, we intend to use the bot credentials to start CI via label, which means the bot will need permission to start CI runs.

Can we add the same permissions we have to @nodejs/collaborators to @nodejs/Bots (or to the user @nodejs-github-bot? cc @nodejs/jenkins-admins

If the bot is to have the same permissions as a collaborator, could it not be added to the @nodejs/collaborators team? We don’t, AFAIK, have a good method for restoring permissions after CI lockdown for security releases (https://github.com/nodejs/build/blob/master/doc/jenkins-guide.md#security-releases) other than manually reentering the entries so I would prefer not to have to add more.

@nodejs/bots already has the same write permission to nodejs/node as @nodejs/collaborators, so I think it should be fine. I suggested giving permissions to the bot team to give it only the least privilege it needs, but your point on it being hard to restore permissions after lockdown makes sense. I'll open an issue on nodejs/admin to request this. Let's keep this one open until we reach a decision there.

Bot was added to collaborators which fixed my issue, so closing
