tools: only fetch previous versions when necessary
Refactor the logic for working out the previous versions of Node.js for the API documentation so that the parsing (including the potential https get) happens at most once per build (as opposed to the current once per generated API doc). Signed-off-by: Richard Lau <riclau@uk.ibm.com> PR-URL: https://github.com/nodejs/node/pull/32518 Fixes: https://github.com/nodejs/node/issues/32512 Reviewed-By: Joyee Cheung <joyeec9h3@gmail.com> Reviewed-By: Myles Borins <myles.borins@gmail.com>
