fix(presets): fix incorrect corepack command for pnpm

[bjoerge]

Description

Deploying a next js app with pnpm currently fails with the following error:

Usage Error: Unsupported package manager specification (pnpxm@latest)

I believe this line is wrong:

temps/crates/temps-presets/src/nextjs.rs

Line 111 in 921ab97

RUN corepack prepare pnpxm@latest --activate

and should instead be

RUN corepack prepare pnpm@latest --activate
