[desktop-lite] Suggested usage of appPort instead of forwardPorts for devconatiner-cli

[daniel-meilak]

Update to the desktop-lite usage documentation:
The devcontainer-cli does not yet support the usage of forwardPorts, as indicated here. Conveniently, we can still use appPort in a similar manner.

This PR simply adds a line of documentation to the README to make users aware of this difference.

Hi @bamurtaugh, here is the small documentation change you asked for in this issue.

[bamurtaugh]

Thanks so much!

[daniel-meilak]

Ah I think I misunderstood how the README is generated. The Automated documentation update undid my change 😆, should I create a new PR that edits NOTES.md instead ?

[bamurtaugh]

Ah thanks for catching this 😄 - @samruddhikhandale would you be able to help advise?

[samruddhikhandale]

Oops 😅

Once this PR got merged, https://github.com/devcontainers/action ran automatically ; which updated the README file based on devcontainer-feature.json and NOTES.md.

Hence, @daniel-meilak can we make the same changes to NOTES.md instead? Thanks!

Hey @samruddhikhandale, here you go, hopefully this time the change persists 😄

Left a minor comment, thank you @daniel-meilak
