Corepack won't be distributed with Node.js 25+ official distributions

per nodejs/TSC#1697 i think we should update the downloads page on the website to add npm install --global corepack to the yarn and pnpm install snippets, to start educating people that this new step is necessary (or will be necessary) @Claudio Wunder. we might also want to recheck with pnpm if this is their preferred installation approach given the change on the node side

This change will occur when v25 releases, see the election results below for more details:

Should we just disabled PNPM and Yarn on download page by adding a condition here:

nodejs.org/apps/site/util/downloadUtils.tsx

Line 235 in b0b5164

compatibility: { semver: ['>= v14.19.0', '>= v16.9.0'] },

or :

• adding snippets to install corepack
• installing these packages with npm
  ...

Nope. Let's not do that.
