The markup command \note has changed: Now it expects a duration, not a 
string anymore. But you can use the internal function \note-by-number 
instead:

\version "2.22.0"

#(use-modules (srfi srfi-60))

#(define-public (format-time-sig-note grob)
   (let* ((frac (ly:grob-property grob 'fraction))
          (num (if (pair? frac) (car frac) 4))
          (den (if (pair? frac) (cdr frac) 4))
          (m (markup #:override '(baseline-skip . 0.5)
                     #:center-column (#:number (number->string num)
                                               #:override '(style . 
default)
                                               #:note-by-number 
(log2-binary-factors den) 0 DOWN))))
     (grob-interpret-markup grob m)))


{
  \override Staff.TimeSignature.stencil = #format-time-sig-note
  \time 4/2
  a4
}

Anyway, it seems to me that, even before that change, you had no 
possibility of writing something like "4 dotted quarter notes". Do you 
need that functionality?
