Fix Vite CJS build warning for Yarn and Vue (#1722)

Fixes #1721 

This fixes the warning about Vite's deprecated CJS build in the
`react/yarn-pnp` and `vue` projects by converting them to an ESM module.
Previously, they were both CJS, most likely due to a simple oversight.

With Vue, it also involved renaming the Cypress config to be a `.js`
file. Vue scaffolds Cypress config files to be a `.ts` file, which in
turn does not work with ESM modules. See [this
issue](cypress-io/cypress#23552) for more
info.
