Remove `addXrayResultUpload` function

[csvtuda]

This PR removes the addXrayResultUpload function and merges it into the configureXrayPlugin function, simply because it makes no sense to have both around when a single one suffices too.

Breaking changes

• removed addXrayResultUpload

• changed configureXrayPlugin parameters which now expects Cypress' on as first parameter:

  await configureXrayPlugin(
  on,
  config,
  {
    jira: {
      url: "https://example.org",
      projectKey: "ABC"
    }
  }
  )
