### Description

Problem with relative links in docs and i18n translation.

### Reproducible demo

https://trofim24.github.io/

### Steps to reproduce

1. Create a new Docusaurus site with `npx create-docusaurus@latest my-website classic -t` command from [instruction](https://docusaurus.io/docs#fast-track)
2. Go to created folder `cd my-website`
3. Copy only one Markdown file and images use
`mkdir -p i18n/fr/docusaurus-plugin-content-docs/current/tutorial-extras/img`
`cp -r docs/tutorial-extras/img/** i18n/fr/docusaurus-plugin-content-docs/current/tutorial-extras/img`
`cp -r docs/tutorial-extras/translate-your-site.md i18n/fr/docusaurus-plugin-content-docs/current/tutorial-extras`
command from [instruction](https://docusaurus.io/docs/i18n/tutorial#translate-markdown-files)
4. Change docusaurus.config.js. Add 'fr' language to locales from [instruction](https://docusaurus.io/docs/i18n/tutorial#site-configuration) and add a navbar item of type localeDropdown from [instruction](https://docusaurus.io/docs/i18n/tutorial#theme-configuration):
`locales: ['en', 'fr']`
and
`{ type: 'localeDropdown', position: 'left', },`
5. Run build use `npm run build` command from [instruction](https://docusaurus.io/docs/deployment)
