[Package Issue]: Git.Git uninstalls extensions during upgrade

Please confirm these before moving forward

• I have searched for my issue and not found a work-in-progress/duplicate/resolved issue.
• I have not been informed if the issue is resolved in a preview version of the winget client.

Category of the issue

Installation issue.

Brief description of your issue

When performing an upgrade to the Git.Git package, an uninstall is performed which removes any extensions, even if they are also installed using winget. Most noteworthy being Microsoft.GitCredentialManagerCore and GitHub.GitLFS. This forces you to keep a list of all extensions and reinstall them manually after any upgrade, and realistically prevents you from ever running upgrade --all as it risks breaking things.

Steps to reproduce

winget install Git.Git -v 2.39.0
winget install Microsoft.GitCredentialManagerCore
winget upgrade Git.Git

Actual behavior

extensions are uninstalled although any configurations in .gitconfig remain.

Expected behavior

extensions to remain in-place or be automatically reinstalled after a git upgrade so functionality remains.

Screenshots and Logs

No response

Start by reproducing the documented commands with Git.Git 2.39.0 and Microsoft.GitCredentialManagerCore, then inspect the Git.Git package upgrade behavior in winget-pkgs. Done means upgrading Git.Git no longer removes winget-installed extensions, or restores them automatically while preserving the existing .gitconfig settings.
