doc: explain the impact of stash.index on --autostash options

Git fork

With 9842c0c749 (stash: honor stash.index in apply, pop modes,

2025-09-29), we did not advertise the connection between the new config
option stash.index and the implicit use of git-stash via --autostash
(which may also be configured). Do so.
