Properly detect preview versions of Visual Studio

[DW01]

Using the new launcher to update the binary release gave me an interesting error. According to the launcher, it knows I have VS installed but thinks it's incomplete. I DO have all the VS workloads required to compile the engine, but I'm running the preview and not the standard release, which makes me think the launcher doesn't properly account for preview versions of VS.

Note for future reference: code checking VS state is not launcher side but prerequisite installer side:

Might be of interest too:

I ran into a similar problem. I have installed the preview version of Visual Studio. Because of this, I cannot install Stride.

I am using VS 2019 Professional Preview, and I had no issue, (except for the part where you need an "older" version of the Build Tools, but that have been fixed). So I think this can be closed, (there haven't been any activity for almost a year)
