Add missing documentation in the official page

Problem/Motivation

Hello, it's been a while since I don't work with the WxT project but I wanted to revisit this again for a potential client, I'm seeing that the latest stable release is 5.4.0 for Drupal Core 10.4, I tried to go to the official installation page to get the DEV release, but I still see some old information:

# Requires PHP 8.1
composer self-update
composer create-project drupalwxt/site-wxt:10.1.x-dev <site-name> --no-interaction

# Requires PHP 8.2
composer self-update
composer create-project drupalwxt/site-wxt:10.2.x-dev <site-name> --no-interaction

Do I need to run this to get the latest 5.4.x-dev release? It looks like it is.

composer create-project drupalwxt/site-wxt:10.4.x-dev wxt104 --no-interaction

I run that command indeed I was able to get 5.4.x-dev but it would have nice to have it

I guess it's the same if you want to get the latest 5.3.x-dev release:

composer create-project drupalwxt/site-wxt:10.3.x-dev wxt103 --no-interaction

I know it's not a big deal, but it would have been nice to have this information handy, same for installing the official releases (https://www.drupal.org/project/wxt/releases/5.4.0)
