This PR fixes a bug seen in PR vercel/vercel#6700 (see logs) where the
tsconfig.jsonis in a parent directory.The
tsconfig-pathspackage was returning an errorMissing baseUrl in compilerOptions.So instead, we'll manually walk up the filesystem to find the relevant
tsconfig.jsonlike we do in@vercel/build-utils.
