Update-Module: Dedupe modules

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

I used ripgrep but any grep tool can be used

Update-Module  -Force -Verbose > .\update.log
rg -n Az\.Accounts.*version .\update.log > 'az accounts.txt'

az accounts.txt
update.log

Expected behavior

Update each unique module/version combo and not have Az.Accounts.2.13.2 for example re-installed multiple times.  Dedupe the unique found versions.  Along with detect dependent vs root modules and only update the root modules and let the dependency functionality install the dependent modules.

Actual behavior

Az.Accounts.2.13.2 and other modules were re-installed multiple times instead of unique module/versions being installed once each.

Error details

No error.  Just unnecessary repetition.

Visuals

No response

Start by reproducing Update-Module -Force -Verbose with the provided ripgrep command and inspect update.log, especially the repeated Az.Accounts entries. Read the Update-Module implementation and its dependency handling; done means each unique module/version is installed once and dependent modules are handled through dependency resolution rather than root-module updates.
