v0.4.0

• Bumps dependencies to the latest version
• Now compatible with Astro version 5
• Astro Hook Update: The plugin now uses a different Astro hook because since the Astro upgrade to version 5 the previous astro:build:start hook runs after the Content Layer API is synced and caches some of its output. As a result, Markdown files generated by the plugin were not included in the production build until the site was built a second time. We are now using the astro:config:setup hook which also has the advantage of files being generated when using the dev command and not only for production builds by @JoblersTune (695cbec)
