Proposal to sunset jx-lens: documentation is misleading as the feature no longer work due current Tekton and Lens versions

[haysclark]

Since March/April of 2022, Tekton breakpoints no longer work for at least two reasons:

1. to support Kubernetes 1.22, the project moved away from the custom fork of Tekton, to Tekton 0.29.0 - 3.2.298
2. the jenkins-x-plugins/jx-lens plug-in stopped working since the release of Lens v6.x; but without breakpoints the plug-in is useless.

Unfortunately, there are a handful of places in the JX blogs, and JX docs that ref this dead feature.

Action items:

• jenkins-x/jx-docs
  • Update Jenkins-X docs about Lens, most added in 0905dc25
• jenkins-x-plugins/jx-lens
  • Update project REAMD.md to mention not supporting Lens v6+
  • Update project REAMD.md to mention project has been deprecated and is no longer supported.
  • 'Archive this repository' in GitHub post updates above
