[BUG] github list team memebrs command results in incorrect response content

**Describe the bug**
The response for the command returns the "MembersSuccessful" text with a missing ": " in between those word.
And the links are the API link instead of the use profiles.

**To Reproduce**
Steps to reproduce the behavior:
1. Send `c!github list-team-members [a team name]`
2. See incorrectly formatted test

**Expected behavior**
Text title is: "GitHub List team Members: Successful"
Member listing text: "1. someusername (https://github.com/someusername)"

**Additional context**
The url for the page should be one of the json properties being incorrectly used.

从 `c!github list-team-members [a team name]` 命令开始，复现 issue 中描述的响应。跟踪响应的格式以及每个成员链接所使用的 JSON 属性。当标题为 "GitHub List team Members: Successful"，且每个成员链接到其 GitHub 个人资料而不是 API URL 时，即表示完成。
