FYI, it should link to its parent:

  /gnu/store/097dmm40lhcf777acqh5i660j4i09k85-tzdata-2022a/share/zoneinfo

(So, yes, you could …/posix/posix/posix/posix/… all night long.)

You could try

  # guix gc --verify=contents,repair

and Guix should detect the mismatch and refresh tzdata from a 
substitute server.

The unsupported alternative would be to bind-mount /gnu/store 
somewhere and manually relink the file.

It wouldn't.

Kind regards,
