docs(readme): Add ascii-movie to 'Bubble Tea in the Wild' section

[gabe565]

Hi! I've used Bubble Tea in a few different projects, but finally have one that feels right to add to the list of example programs. This PR adds a link to gabe565/ascii-movie to the readme.

ASCII Movie plays the Star Wars telnet movie locally, over SSH, or over Telnet and uses Bubble Tea for its TUI.
