Carrying the legacy version is a maintenance burden, and has in fact become out of date failing a test since the 2.23 release, without anyone noticing until now. So users would be getting a hint to fall back to a potentially buggy version of the tool. We used to shell out to git config to get the useBuiltin configuration to avoid changing any global state before spawning legacy-stash. However that is no longer necessary, so just use the 'git_config' function to get the setting instead. Similar to what we've done in d03ebd411c ("rebase: remove the rebase.useBuiltin setting", 2019-03-18), where we remove the corresponding setting for rebase, we leave the documentation in place, so people can refer back to it when searching for it online, and so we can refer to it in the commit message.
