[Clarification] run wsl.exe --update in EACH windows 10 user command prompt, not just elevated command prompt

[Growflavor]

Is your feature request related to a problem:

In case others think like me and thought that just running wsl.exe --update in the elevated command prompt was sufficient:

WSLg worked fine for the distributions I installed in my windows 10 admin account,
but for distributions installed in my various other windows 10 user accounts, I was getting the 'display error', in other words, I encountered symptoms similar to those described in issue #793 -- specifically:

"When I do a "ls" on my Ubuntu WSL /mnt folder, I only see "c" and "wsl" folders
GUI Linux apps don't work and I noticed running "echo $DISPLAY" in Ubuntu WSL doesn't output anything"

In my case, running wsl.exe --version returned the expected information in my admin elevated command prompt:

C:\WINDOWS\system32>wsl --version
WSL version: 1.2.5.0
Kernel version: 5.15.90.1
WSLg version: 1.0.51
MSRDC version: 1.2.3770
Direct3D version: 1.608.2-61064218
DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp
Windows version: 10.0.19045.3570

however, in my windows user terminals wsl.exe --version returned only the --help info which led me to the following comment in this post:

https://superuser.com/questions/1778332/how-can-i-find-my-wsl-release-number-not-version-not-build-not-kernel-not

"If wsl.exe --version simply returns help text (very likely given the older kernel that you are showing), then you are running an older release of WSL."

sure enough, after running wsl.exe --update in each of my windows 10 user command prompts (i.e not just my elevated command prompt) then wsl.exe --version worked as expected in my user shells and WSLg now also works as expected in my re-installed distributions in my various windows 10 user accounts.

Describe the solution you'd like:

If running wsl.exe --update in each user command prompt is the expected requirement/behavior, then for people who think like me it likely would be helpful to add an explanatory note in the WSLg README.md

https://github.com/microsoft/wslg#install-instructions-existing-wsl-install

since the current language appears to indicate "run the command wsl --update from an elevated command prompt."

Describe alternatives you've considered:

running wsl.exe --update in each user command prompt resolves the issue. I just do not know if that is the expected behavior.

Thank you for WSLg!
