The new enabledApiProposals should be used instead of the deprecated enableProposedApi in the official samples that use proposed APIs.

The samples that still use the old method are:

• inline-completions
  • inlineCompletions
• terminal-sample
  • terminalDataWriteEvent
  • terminalDimensions

Note that even though comment-sample and extension-terminal-sample use enableProposedApi, they do not currently use any actual proposed APIs. Also, extension-terminal-sample refers to "Proposed API" in its README, but those APIs were finalized.
