bug#31194: 26.1; `display-buffer-in-major-side-window' was renamed without an alias.

[Phil Sainty]

Changelog.3 records that `display-buffer-in-major-side-window' was
renamed to `window--make-major-side-window'; but no alias from the old
name to the new name was added for backwards-compatibility.

I have at least one library installed (which-key.el) which triggers an
error on this account.
