Changes

Based on feedback:

• Explicitly mentions in the installation instructions that tkn is the command name of the Tekton CLI.

• Provide a better description of when the installation of Tekton Pipelines is complete. Namely, when both tekton-pipelines-controller and tekton-pipelines-webhook are Ready. Added output example.

• Consistent capitalization of "Task", "TaskRun", "Pipeline", "PipelineRun", "Workspace", and "Step". Since these are first class objects with a specific meaning within Tekton, we treat them as nouns when writing docs.
