Use Appium to tests and generate recording of Nokee's IDE integration

[lacasseio]

Appium support classic Windows application testing which we can use to test common developer workflow inside the IDE. Microsoft also released a tool called WinAppDriver UI recoder. Appium seems to also support native mac application.

We could and should use the same mechanic to generate short gifs/videos to display in the documentation. Generating those videos are time-consuming but also affect negatively the project perception when they fall out-of-date. It's unrealistic to keep those videos up-to-date manually.

I marked this issue as a good first issue because the contributor can experiment outside the codebase on a solution that we can connect to the project as a follow-up step. We will also need to break down this issue into several on. The first parallel steps are:

• 1 tests using Appium, say launching a build from the IDE, for each individual IDE (1 for Visual Studio and another for Xcode)
• 1 recording using Appium, say launching a build from IDE, for each individual IDE (1 for Visual Studio and another for Xcode)
