Description: Add Icon file for the RHEL WSL release tarball for display within the WSL application.

Reason: To help users differentiate between multiple Windows Subsystem for Linux distros if one of those happen to be a RHEL instance 

 
Details for the standard file:

Custom Build file for a WWSL ( basically a tar ball )

Add the WSL distribution configuration file

The distribution configuration file, /etc/wsl-distribution.conf, defines how the Linux distribution should be configured when first launched by the user. This file can be used to interactively create a user account, show a license agreement, etc.

Here is a sample /etc/wsl-distribution.conf file:
Bash

1. /etc/wsl-distribution.conf

[oobe]
command = /etc/oobe.sh
defaultUid = 1000
defaultName = my-distro

[shortcut]
enabled = true
icon = /usr/lib/wsl/my-icon.ico

[windowsterminal]
enabled = true
ProfileTemplate = /usr/lib/wsl/terminal-profile.json

So we would need a simple /etc/wsl-distribution.conf file for the WLS builds

EXAMPLE:

File Contents of: /etc/wsl-distribution.conf
Note: this file in the tarball

[shortcut]
enabled = true
icon = /usr/lib/wsl/rhel.ico

So likely whomever packages the images would need to add this to their build script.
