[ScriptedAlchemy]

Summary

add support for rootOutputDir to locate chunk paths in node federation plugin

Webpack version:

   const outputName = this.compilation.getPath(
          jsModulePlugin.getChunkFilenameTemplate(
            this.chunk,
            this.compilation.outputOptions,
          ),
          { chunk: this.chunk, contentHashType: 'javascript' },
        );
        rootOutputDir = getUndoPath(
          outputName,
          this.compilation.outputOptions.path || '',
          false,
        );

in template:

  return template.asString([
    `if(!${federationGlobal}){`,
    template.indent([
      `${federationGlobal} = {`,
      template.indent([
        `initOptions: ${initOptionsStrWithoutShared},`,
        `chunkMatcher: function(chunkId) {return ${matcher}},`,
        `rootOutputDir: ${JSON.stringify(rootOutputDir || '')},`,
        `initialConsumes: undefined,`,
        'bundlerRuntimeOptions: {}',
      ]),
      '};',
