We don't really have a concept in Tekton of something called a "Workspace volume",
but multiple READMEs now refer to it.
This commit removes the term "Workspace volume" in favor of simply "Workspace".
Changes include:
- adds version label
- adds a minimum pipeline versions supported by the task
- adds display name for task
- adds tags for task
- modified description to add a summary
This patch moves the terraform-cli files to the task directory and
renames the yaml file
- The yaml filename is changed to match the resource name
- Modifies the path for install task command in readme file
Issue: #386
