fix(nx): project.targets.build.options could be undefined

[NexZhu]

This fix the issue that the last line below will throw an error if build.options is undefined:

export async function getNxTrueAffectedProjects(
  cwd: string
): Promise<TrueAffectedProject[]> {
  const projects = await getNxProjects(cwd);

  return projects.map(({ name, project }) => {
    let tsConfig = project.targets?.build?.options.tsConfig;

TypeError: Cannot read properties of undefined (reading 'tsConfig')
