multiple versions of vim exist in my system, but cannot be uninstalled.

Steps to reproduce

1. install the MacVim.app (8.1.950) first
2. update MacVim when update program pops. (8.1.1517)
3. Now I tried to install the latest version, it is (8.2.3455)
4. When I right click and open with MacVim, three version exits in the "open with" list.

I tried to uninstall them, only the latest version can be removed.

So my questions are 1) how to remove all of them, 2) How to keep the latest one only, if I update it?

Expected behaviour

keep the latest one only

未提及文件、测试或代码入口点。首先在 macOS 10.14.6 上重现 MacVim.app 的更新流程，然后验证旧版本不再出现在 Open With 列表中，并且只保留最新版本。
