Getting Started: Update instructions for making 8080 public

[alisonjo315]

Describe the bug

There's no "Remote Explorer" button anymore. To make a workspace website (8080) public, go to the "Ports" tab.

As such, the "Getting Started" instructions just need a little updating.

To Reproduce

• Go to a DrupalPod workspace.
• Read "Getting Started"
  • TO DO: Add instruction for getting the "Getting Started" panel back after you close it (asked on Slack).
• Step __ (at the time of writing) references a "Remote Explorer" button that doesn't exist.

Expected behavior

This step should instruct users to go to the Ports tab (adjacent to the Terminal tab).
