Fix: Aliased pages not included in published subgraph

[logseq-cldwalker]

This PR fixes #4143. To reproduce:

1. create a public page with an alias
2. create another public page that has two links, one to the page and one to the page alias
3. Be sure logseq/config.edn has :publishing/all-pages-public? false
4. Run bb dev:publishing ... to build the publishing app per https://github.com/logseq/logseq/blob/master/docs/dev-practices.md#babashka-tasks
5. The aliased link should correctly redirect to the original page

For these first two steps, you can QA the exact pages I used by using the logseq-export and logseq-import CLIs and the following export.edn content:

[#:file{:content
        "public:: true\n\n- https://github.com/logseq/logseq/issues/5280\n\t- [[page 5280]]\n\t- [[page 5280-alias]]",
        :path "journals/2023_06_06.md"}
 #:file{:content "alias:: page 5280-alias\npublic:: true\n\n- content",
        :path "pages/page 5280.md"}]
