🍿 Minor Changes

• #12539 827093e Thanks @bluwy! - Drops node 21 support

• #12083 9263e96 Thanks @Princesseuh! - Reworks the experience of creating a new Astro project using the create astro CLI command.

  • Updates the list of templates to include Starlight and combines the “minimal” and “basics” templates into a new, refreshed “Basics” template to serve as the single, minimal Astro project starter.
  • Removes the TypeScript question. Astro is TypeScript-only, so this question was often misleading. The “Strict” preset is now the default, but it can still be changed manually in tsconfig.json.
  • astro check is no longer automatically added to the build script.
  • Added a new --add flag to install additional integrations after creating a project. For example, pnpm create astro --add react will create a new Astro project and install the React integration.
