chore: remove the step to run unit tests and typecheck before git commit (#658)

#### What type of PR is this?

/kind improvement
/milestone 2.0

#### What this PR does / why we need it:

移除在 Git Commit 之前运行单元测试和类型检查的步骤。因为目前 main 分支处于保护分支，无法直接推送代码。所以仅在 PR 中的 Action 来运行这两个步骤即可。

#### Does this PR introduce a user-facing change?

```release-note
None
```
