Add README install for Yarn 2+ using 'yarn dlx'
This commit brings the README up to date with yarn latest.
Yarn 3 is the latest stable version of yarn,
such as installed by running this command:
$ yarn set version latest
Yarn 2 introduced the new command 'yarn dlx' which downloads and executes a package in a temporary environment. This is the preferred way to work with Yarn 2 and Yarn 3, as explained on the Yarn website page about 'yarn dlx'.
See https://yarnpkg.com/cli/dlx
Yarn 1 is helpful to still have in the instructions because some developers still use it for historical reasons, such as needing to manage a third-party package that has not been updated to work with Yarn 2 or Yarn 3. However, the Yarn 1 instructions do not work correctly with Yarn latest.

We (Yarn) should update our documentation but you can still use yarn create in v2 and up, under the hood it calls yarn dlx create-
For what it's worth, I highly prefer the explicit yarn dlx create-react-app rather than yarn create react-app doing it under the hood.
Explicit security is a valuable feature IMHO.
My context is a pain point with a vendor where some developers are on older Yarn (not Yarn 3) and the vendor is pointing to this CRA repo saying yarn create react-app is the official CRA way, and there's no info on the CRA page about yarn dlx, so our vendor documentation is not adding any information about yarn dlx at this time. This is causing confusion among the developers on both sides. An easy compromise is to have CRA explain both ways.
