Remove swc templates from Getting Started page

[vacekj]

Description

This commit removes the react-swc-ts and react-swc templates as they no longer exist.

However, I propose it should still be somehow mentioned that there is an option to use swc in place of Babel. I'm leaving the way to approach this up to discussion.

They exist. -swc packages are special templates derived from the React templates with the Vite plugin swapped to @vitejs/plugin-react-swc. You can pass them to --template.
