You have an old checkout?  I'm on a pretty recent HEAD and docstring of
text-scale-adjust links to global-text-scale-adjust.

    This command is a special-purpose wrapper around the
    ‘text-scale-increase’ command which makes repetition convenient
    even when it is bound in a non-top-level keymap.  For binding in
    a top-level keymap, ‘text-scale-increase’ or
    ‘text-scale-decrease’ may be more appropriate.

    Most faces are affected by these font size changes, but not faces
    that have an explicit ‘:height’ setting.  The two exceptions to
    this are the ‘default’ and ‘header-line’ faces: they will both be
    scaled even if they have an explicit ‘:height’ setting.

    See also the related command ‘global-text-scale-adjust’.

      Probably introduced at or before Emacs version 28.1.
