blog: RSS and Atom feeds ignoring baseUrl

[jsamr]

🐛 Bug Report

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.

Description

RSS <link>, Atom <id>, <link> and <icon> are missing the baseUrl path from configuration, misleading feeds readers. Note however that entries are not affected by this bug.

Have you read the Contributing Guidelines on issues?

Yes

To Reproduce

1. Run npx @docusaurus/init@latest init docusaurus-base-url-bug classic
2. Add baseUrl: "/test/" config in docusaurus.config.js
3. Make sure you are using the classic preset
4. Activate blog feeds with { blog: feedOptions: {type: 'all' } } in classic preset config object.
5. Run yarn build
6. Inspect atom.xml and rss.xml files in build/blog

Expected behavior

RSS channel root link is including baseUrl

<rss version="2.0">
    <channel>
        <link>https://domain.com/test/blog</link>
    </channel>
</rss>

Atom feed id, link and icon root tags are including baseUrl

<feed xmlns="http://www.w3.org/2005/Atom">
    <id>https://domain.com/test/blog</id>
    <link rel="alternate" href="https://domain.com/test/blog"/>
    <icon>https://domain.com/test/favicons/favicon-32x32.png</icon>
</feed>
