xref_ignore_test fails for rebar3 3.27.0 and Erlang 29.0-rc2

Hi!

Currently, the xref_ignore_test fails for rebar3 3.27.0 and Erlang 29.0-rc2. It prints the following output:

%%% rebar_xref_SUITE ==> xref_ignore_test: FAILED
%%% rebar_xref_SUITE ==> 
Failure/Error: ?assert(lists : member ( { SomeMod , notavailable , 1 } , UndefFuns ))
  expected: true
       got: false
      line: 196

I suspect that this happens because of the changes from the following commit in OTP: erlang/otp@6f398fb
