Is your feature request related to a problem? Please describe.
The Tekton Dashboard Helm chart is currently hosted in the edp-tekton repository. However, this chart is better suited for inclusion in the edp-cluster-add-ons repository, which is designed to centralize and manage cluster-wide add-ons. Keeping the chart in edp-tekton creates fragmentation and complicates the management of add-ons for users.

Describe the solution you'd like
Move the Tekton Dashboard Helm chart from edp-tekton to the edp-cluster-add-ons repository. This migration will streamline the organization of add-ons, making it easier for users to manage and deploy all necessary components from a single source.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
Ensure that all migration steps, including updating documentation, CI/CD pipelines, and any dependencies, are addressed.
