feat: Align chart for ingress TLS configuration(#178)

[alezander86]

Description

This pull request introduces updates to the Tekton Pipelines Library Helm chart, focusing on improving the dashboard ingress configuration for better flexibility and usability. Changes have been made to README.md, _helpers.tpl, ingress.yaml, and values.yaml files to allow a more dynamic setup of the Tekton dashboard URL and to facilitate the configuration of TLS for the ingress. These enhancements aim to provide users with a more intuitive way of setting up the Tekton dashboard access, especially in environments with varying DNS configurations.

Fixes

Updated ingress configuration to support dynamic dashboard URL based on the namespace or a specified host.
Improved TLS configuration documentation and options for the dashboard ingress.
Streamlined dashboard ingress setup for enhanced user experience.
Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How Has This Been Tested?

The updates were tested by deploying the modified Helm chart in a Kubernetes cluster with different configurations for the dashboard ingress host and TLS settings. The deployment was verified to work as expected in scenarios with and without specified hosts, and with custom DNS settings.
