fix(@angular-devkit/build-angular): default preserve symlinks to Node.js value for esbuild

clydin · dgp1130 · commit 97716969c243 · 2022-12-05T11:08:35.000-08:00
When using the experimental esbuild-based browser application builder, the `preserveSymlinks`
option will now default to the value of the Node.js `--preserve-symlinks` argument. This removes
the need to manually specify the option in two places if executing the build manually with Node.js
or via the `NODE_OPTIONS` environment variable. This behavior mimics that of the default Webpack-based
builder.
