CI's newer pnpm warns "the pnpm field in package.json is no longer read"
and still failed build-web with ERR_PNPM_IGNORED_BUILDS. The settings moved
to pnpm-workspace.yaml in pnpm 10+. Put onlyBuiltDependencies (esbuild,
@swc/core) and ignoredBuiltDependencies (react-vertical-timeline-component)
there and drop the dead package.json field. Verified with a cold
`pnpm install --frozen-lockfile`: postinstalls run, no error, lockfile
unchanged.
