I do not think update-ref is a tool to modify a symbolic-ref.
Moreover, the mention of "ref:" is meant to be for those who are
overly curious for their own good and go peek into their .git/
directory; script writers should not have to know such an
implementation detail.

: ask what the current state is.
$ git symbolic-ref refs/remotes/origin/HEAD
fatal: ref refs/remotes/origin/HEAD is not a symbolic ref

: set it
$ git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main

: inspect the result
$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/master

Thanks.
