## @important If pnpm is downloading node during the build, that's a bandwidth-expensive mistake.
##            Node already exists in the docker image at /usr/local/bin/node.
##            We should use the node version that exists in the docker image.
##            The only thing that should be downloaded by corepack is pnpm.
##            The reason we explicitly set a pnpm version here is because we want to have pnpm cached.
##            We haven't copied any .npmrc or package.json files at this point in the build, so corepack has no way of knowing which version to get.
##            There might be a more optimal way of doing this that doesn't require syncing this version with the version in package.json
##            but I'm not sure what that would look like.
##
## @important match the pnpm version between all pnpm workspace packages or multiple versions of pnpm will get installed (slow)
