@vue/cli-plugin-eslint 在使用typescript和eslint的时候，默认配置没有包含对ts文件的检查

3.6.0

个人认为应该在applyTS方法中加上lint-staged对ts默认的支持

Steps to reproduce

创建项目的时候选择typescript，lint选项使用eslint standard

What is expected?

在生成的项目package.json中应该包含ts文件，例如：

  "lint-staged": {
    "*.{js,vue,ts}": [
      "vue-cli-service lint",
      "git add"
    ]
  }

What is actually happening?

实际上这个lint-staged配置是默认去检查写死的js和vue后缀

  "lint-staged": {
    "*.{js,vue}": [
      "vue-cli-service lint",
      "git add"
    ]
  }

---

这样会在commit的时候丢失对ts文件的检查，只有独立使用npm run lint才会去检查
