message: expand polysite example

  In Lagoon, the same Git repository can be added to multiple projects, creating what is called a polysite. This allows you to run the same codebase, but allow for different, isolated, databases and persistent files. In `.lagoon.yml` , we currently only support specifying custom routes for a polysite project. The key difference from a standard project is that the `environments` becomes the second-level element, and the project name the top level.
  +To utilise this, you will need to:
  +
  +1. Create two (or more) projects in Lagoon, each configured with the same gitUrl and production branch, **named as per the .lagoon.yml** (i.e `poly-project1` and `poly-project2` below)
  +2. Add the deploy keys from each project to the git repo
  +3. Configure the webhook for the repo (if required) - you can then push/deploy. Note that a push to the repo will simultaneously deploy all projects/branches for that gitUrl
  +
  **Example:**
  ```yaml title=".lagoon.yml"
  -example-project-name:
  +poly-project1:
  environments:
  main:
  routes:
  - nginx:
  - - example.com
  + - project1.com
  +poly-project2:
  + environments:
  + main:
  + routes:
  + - nginx:
  + - project2.com
  ```
