Add rtools and add registry for R

[Yunuuuu]

Thanks for the scoop bucket repo.

This commit should resolve #30, Note that the same issue reported in Positron also exists in RStudio.

Additionally, this commit adds support for Rtools 40–44 for R versions > 4.0.0.

• From R 4.2.0 onward, R inspects the environment variable RTOOLS42_HOME.
• From R 4.3.0, it inspects RTOOLS43_HOME.
• From R 4.4.0, it inspects RTOOLS44_HOME.

As a result, rtools42, rtools43, and rtools44 now set their respective environment variables.

For R versions ≥ 4.0.0 and < 4.2.0, r-release will create Renviron.site and add: PATH="${RTOOLS40_HOME-C:/rtools40}/usr/bin;${PATH}". This follows the same approach as R ≥ 4.2.0. So rtools40 also sets RTOOLS40_HOME.

My original R manifest was based on yours (should be R version 3.5), and I’ve maintained my own Scoop bucket repo at https://github.com/Yunuuuu/jade. I have used these configurations on multiple computers in my labs and for my senior and junior labmates (from R 3.5 to the latest version), and they have worked well.

I hope these improvements enhance the official R bucket repo!

Sorry for the delay - I missed this PR when you opened it.

To be honest I know use rig to install and manage R, and no more scoop. So I scoop install rig and then use rig directly.

I know I added R to this repo, but I may have not pay attention that it was already in official bucket

rtools is in versions

Notes       : This version requires UCRT, which is part of Windows since Windows 10 and Windows Server 2016.

              For source packages installation, please install 'rtools'.
              For 32bit edition, please install 'versions/r41'.

              You'll need to type 'r.exe' to run R, because in Powershell 'r' runs the last command. Alternatively 'rterm'
              can be used to start the interactive R terminal session.

              You can remove Powershell's 'r' command with:
                  rm alias:\r

              ... but this only affects your current session: if you'd like to remove it for all future sessions you need
              to add the command above to your Powershell profile.

              Annoying, right?! You might want to check out Pshazz (scoop install pshazz)--this has a plugin to remove
              some crazy aliases from Powershell, as well as many other improvements.

Is your solution different than the one provided in the default buckets?

I was thinking of retiring the r one in here toward using the main bucket one.

So I am hesitant to add more to maintain. But I trust this works, I just don't use it directly anymore.
