docs: use svelte cli instead of create-svelte and svelte-add

With version 5 of svelte, svelte-add and create-svelte commands
are deprecated. Svelte cli is the new way to go so the docs have been
updated to replace:

- npm create svelte@latest my-project by npx sv create my-project
- npx svelte-add@latest tailwindcss by npx sv add tailwindcss
