keyman: replace removed inquirer prompt type 'list' with 'select'

inquirer v10 removed the legacy 'list' prompt in favour of 'select', so
every list-style prompt — starting with the main menu — died with
"Prompt type \"list\" is not registered" on any real run against the
declared ^14 dependency. The tests never saw it because they all mock
inquirer.prompt, which accepts any type string. Choice shapes and the
'default' option are unchanged; 'select' takes them as-is.

Bump to 0.7.2 to ship the fix.
