Change wording for Windows/WSL packages in docs (#26489)

Changes the wording around Windows/WSL install information for packages.

I encountered a user who was attempting to install Chapel for
multi-locale execution with GASNet. They were building from source (I
think thats just because what they were directed to), but they could
have just installed the package and saved a lot of time. This made me
wonder if our docs should mention the Linux packages on WSL, and I found
they do but they also said only shared memory was supported. This PR
updates that wording.
