How to use the @s-ui/helpers/packages.getPackageJson function in @s-ui/helpers

.then(() => {
        // Create release commit
        const {version} = getPackageJson(cwd, true)
        return serialSpawn(
          [['git', [`commit -m "release(${packageScope}): v${version}"`]]],
          {cwd}
        )
      })
      .then(() => serialSpawn(docCommands))

.then(() => {
        // Create release tag
        const {version} = getPackageJson(cwd)
        return serialSpawn(
          [['git', [`tag -a ${tagPrefix}${version} -m "v${version}"`]]],
          {cwd}
        )
      })
      .then(() => serialSpawn(publishCommands, {cwd}))
