DATASTAR: Write File

Writes a file whose contents reference pipeline variables. Typical use is producing a JSON properties file that later steps (or the release pipeline) read:

{
  "WorkItem": "$(WorkItem)",
  "Version": "$(Rev)",
  "BuildId": "$(Build.BuildId)",
  "BuildNumber": "$(Build.BuildNumber)"
}

Any pipeline variable can be used. $(Rev) is a task-specific shortcut: it resolves to the digits after the final period in $(Build.BuildNumber). For example, a build number of 1234.99 makes $(Rev) equal to 99.
