rbx_reflector does not always reflect the current Roblox Studio install's version

[kennethloeffler]

While I was working on #302, I noticed that the Version field in the database stayed at [0, 578, 0, 5780566] after I ran rbx_reflector, even though my Roblox Studio was on a later version:

{
  "Version": [
    0,
    578,
    0,
    5780566
  ],
<truncated>

I discovered that rbx_reflector is grabbing the version from a Roblox endpoint:

rbx-dom/rbx_reflector/src/studio_version.rs

Line 11 in fd147f7

reqwest::blocking::get("https://clientsettings.roblox.com/v2/client-version/WindowsStudio")

Right now, it sends me back this:

{"version":"0.578.0.5780566","clientVersionUpload":"version-1f12a0b5b1bf44ce","bootstrapperVersion":"1, 6, 0, 5780566"}

Clearly, newer versions of Roblox Studio can ship before this endpoint bumps versions. In any case, there is no guarantee that the local Roblox Studio install is the same version as the one obtained from this endpoint, so rbx_reflector shouldn't do this. Instead, it should probably obtain the version from the injected plugin, like generate_reflection:

rbx-dom/generate_reflection/plugin/main.lua

Lines 1 to 13 in fd147f7

	local HttpService = game:GetService("HttpService")
	local SERVER_URL = "http://localhost:22073"
	local version = string.split(version(), ".")
	local major = tonumber(version[1])
	local minor = tonumber(version[2])
	local patch = tonumber(version[3])
	local build = tonumber(version[4])
	HttpService:PostAsync(SERVER_URL .. "/info", HttpService:JSONEncode({
	version = {major, minor, patch, build},
	}))

This ensures that it always gets the version of the Roblox Studio actually installed on the machine, which is exactly what we want here.
