Create lab environment

### Background on the problem the feature will solve/improved user experience
Developers learn best by example and demonstration. We would like you to create a tutorial, or lab, for new developers to run through and get the application running in a sandbox environment. ​

See [example lab](https://ide.skillsnetwork.site/guided_projects/legit-info-cfcfrj) from Legit Info project.


### Describe the solution you'd like
Lab that walks learner through Open Sentencing solution and sets up dependencies to run the application.

### Tasks
- Follow the documentation and run the application​
- Sign into the [Author Workbench](https://author.skills.network/users/sign_in) with IBM ID
- If you don't have IBM Id, you can create one after clicking on the IBMid button.
- Once inside the work bench, link your GitLab account. You will have to create a [GitLab](https://about.gitlab.com/) account if you don't have one already.
- The lab is already created for you. Provide your email to the IBM mentor after completing the steps above to gain access.

### Acceptance Criteria
Functioning lab in the sandbox environment

リポジトリのドキュメントとリンクされているLegit Infoのサンプルラボから始め、続いてOpen Sentencingアプリケーションのセットアップと依存関係の導入手順を確認してください。ラボでは、新しい開発者がAuthor WorkbenchとGitLabのリンクプロセスを進められるように案内し、動作するアプリケーションサンドボックスを完成させる必要があります。
