DOC: Inconsistency in Setting Up Dev Env
#### Location of the documentation

https://pandas.pydata.org/pandas-docs/dev/development/contributing_environment.html#installing-a-c-compiler

**Note**: You can check the latest versions of the docs on `master` [here](https://pandas.pydata.org/docs/dev/).

#### Documentation problem

> You will need Build Tools for Visual Studio 2017.
> 
> Warning
> 
> You DO NOT need to install Visual Studio 2019. You only need “Build Tools for Visual Studio 2019”

#### Suggested fix for documentation

Someone should update. This is confusing for me because I'm trying to set one up.
