ncc build fails with bun when node isn't installed

[benjiewheeler]

When using ncc in a docker build with the oven/bun image, the build fails with the following error:

1.687 error: Module build failed (from ../tmp/@vercel/ncc--bunx/node_modules/@vercel/ncc/dist/ncc/loaders/ts-loader.js):
1.687 Error: Could not load TypeScript compiler with NPM package name `/tmp/@vercel/ncc--bunx/node_modules/@vercel/ncc/dist/ncc/typescript.js`. Are you sure it is correctly installed?

Adding nodejs to the Dockerfile solves this issue:

# build-stage
FROM oven/bun:1.0.6-alpine as build

# vvvvvvvvvvvvvvvvvvvvvvv
# uncommenting this line solves the issue
# RUN apk add --no-cache nodejs
# ^^^^^^^^^^^^^^^^^^^^^^^

WORKDIR /build

# copy package.json & lockfile
COPY package.json bun.lockb ./

# install dependencies
RUN bun install

# add source code

# build
RUN bun x @vercel/ncc build ./src/index.ts -o ./dist

# run stage

# copy the files from the build stage
