Request to upgrade Jenkins to a new version

[LinuxSuRen]

I suggest upgrading the Jenkins version to a new version, such as 2.289.3. Maybe we can also consider upgrading parts of the Jenkins plugins.

Why not use the latest version?

Actually, Jenkins does not have a real LATEST version. We should always talk about a specific version instead of the latest. No one knows what the latest is. The latest version is always changing.

For the Jenkins core, I don't recommend using 2.303.3 which is the latest from this point. I know that the newer version must already fix some important issues (such as security issues). But it also may import some other unknown issues.

Potential Jenkins core

The candidate version is 2.289.3 which is the last big LTS version.
