suggest a better solution for monorepo building without tscalias.

we have similar setup but ends up with better solution:
using tsconfig-paths-webpack-plugin with following code can avoid touch build result

import { TsconfigPathsPlugin } from 'tsconfig-paths-webpack-plugin';

  const worker = await Worker.create({
    connection,
    workflowBundle:
      env.NODE_ENV === 'production'
        ? {
            codePath: path.resolve(__dirname, './workflow-bundle.js'),
          }
        : await bundleWorkflowCode({
            workflowsPath: path.resolve(
              process.env['NX_WORKSPACE_ROOT']!,
              'packages/libs/temporal-workflow/src/workflows',
            ),
            webpackConfigHook: config => {
              if (config.resolve!.plugins == null) {
                config.resolve!.plugins = [
                  new TsconfigPathsPlugin({
                    configFile: path.resolve(
                      process.env['NX_WORKSPACE_ROOT']!,
                      'packages/libs/temporal-workflow/tsconfig.lib.json',
                    ),
                  }),
                ];
              } else {
                throw new Error(`config.resolve.plugins is not null`);
              }
              return config;
            },
          }),

Fwiw we are also using TsconfigPathsPlugin and it works quite well.

Regardless, cheers for putting together this repo as it was a great sanity-check while trying to get NX + Temporal working together.

Are you open to PRs? I learned a few things that hard way when it came to NX + Temporal and I would be happy to contribute them.
