Include Git Username and Email Setup In Initial Workspace Setup

When I create a new workspace and start doing work in it, the first time I try to commit my code in Git using the source control tab on the left side of the IDE, it fails because my username and email haven't been set up in the git executable for that workspace.

This means I have to go to terminal and run the commands:

```
git config --global user.email "some@email.com"
git config --global user.name "Firstname Lastname"
```

I feel that, if the user were prompted for this information during setup of the workspace, there wouldn't be a need for a user to drop into the terminal and run UNIX CLI commands to complete their workspace setup.

Right now I work around this by running a custom script upon creating a new workspace.

首先检查初始工作区设置流程，以及首次提交失败的源代码管理选项卡。确定如何处理新工作区的 Git 身份配置，并定义提示和持久化行为。当新创建的工作区无需终端命令即可完成首次提交时，即表示完成。
