record: use "ui.extractchoices()" to get the list of available responses

Before this patch, record extension gets the list of available
responses from online help document of "hg record" in the tricky way,
even though the value passed to "ui.promptchoice()" has enough (maybe
i18n-ed) information.

This patch uses "ui.extractchoices()" to get the list of available
responses.
