Org 9.5 changed the default value of org-adapt-indentation from t to
nil, as that seemed to be what a lot of users expect[1], so
org-indent-line should not indent the second line in Emacs 28 onward
unless configured otherwise:

- setting org-adapt-indentation back to t will make Org indent by
  inserting whitespace;

- alternatively, enabling org-indent-mode will make Org "soft-indent"
  with text properties.


[1] Org 9.4 made RET and C-j obey electric-indent-mode like they do in
    most other major modes.  Since org-adapt-indentation was t by
    default, this led to many dismayed reports on emacs-orgmode that
    "RET now messes up indentation", indicating that these users did not
    expect their prose to be indented.
