Marketplace gh login: read gh 2.101's device-code wording

gh 2.101.0 (the image's) prints "! One-time code (XXXX-XXXX) copied to
clipboard" and "Press Enter to open https://github.com/login/device in
your browser...". parse_device_prompt only knew "one-time code:", so no
code event went out and Enter was never pressed: gh sat at its prompt
until the 10-minute timeout. Match the label case-insensitively, accept
":" or "(" before the code, and require something after it so a code cut
by a frame boundary is not taken early.
