gh pr list: no support for --head <owner>:<branch> syntax #10945
Description
Describe the bug
gh pr list only supports the --head <branch> syntax but not --head <owner>:<branch>.
Meanwhile, gh pr create --head <owner>:<branch> is supported since v2.71.0 (added by #10513 in fixing #575).
Need to check other options which accept a branch name.

Steps to reproduce the behavior
--head "typos" finds two closed PRs in latex3/latex repository.
$ GH_PAGER="" gh -R latex3/latex3 pr list --state all --head "typos"
Showing 2 of 2 pull requests in latex3/latex3 that match your search
ID TITLE BRANCH CREATED AT
#1610 fix small typos mbertucci47:typos about 6 months ago
#392 Typos in the intro to the l3tl documentation EvanAad:typos about 7 years ago
But when specific owner name is provided (`--head ":typos"), no PR is found.
$ GH_PAGER="" gh -R latex3/latex3 pr list --state all --head "mbertucci47:typos"
no pull requests match your search in latex3/latex3
$ GH_PAGER="" gh -R latex3/latex3 pr list --state all --head "EvanAad:typos"
no pull requests match your search in latex3/latex3
Logs
Adding GH_DEBUG=api, it seems the only useful info is that the <owner>:<branch> was correctly passed on to GraphQL variables
$ GH_DEBUG=api GH_PAGER="" gh -R latex3/latex3 pr list --state all --head "mbertucci47:typos"

GraphQL variables: {"headBranch":"mbertucci47:typos","limit":30,"owner":"latex3","repo":"latex3","state":["OPEN","CLOSED","MERGED"]}
