Breaking Change Notes

Docusaurus v3

• New version uses @mdx-js/react v3. The syntax should now escape the < and { characters with a backslash in .md files. In current TruBudget typedoc generated api docs, this is not being done. The fix is to add the package @types/react to the TruBudget api folder, which will generate correct .md files.
• New version has some structural changes, thus the @type imports had to be renamed (such as from DocPage to DocRoot) More info: Relevant Docusaurus PR
• New version uses react v18 so react is also upgraded.
• Whatever package was providing the classnames, is no longer providing it as a dependency. That's why it is now added manually into dependency list.
• Packages plugin-content-docs and @docusaurus/theme-search-algolia are removed from dependencies. These already come with the classic preset of the Docusaurus and are configured under docusaurus.config.js
