<#
.SYNOPSIS
This script publishes a new release of Dev Proxy to the Windows Package Manager (winget).

.DESCRIPTION
This script updates the manifest files for Dev Proxy to create a new release. It copies the old version files to the new version folder, replaces the old version number with the new version number in the files, and updates the installer hash in the Microsoft.DevProxy.installer.yaml file. The script then creates a new branch, commits the changes, and pushes the branch to the remote repository. Finally, the script creates a pull request with the new version information.

.PARAMETER OldVersion
The version number of the current release in semver format.

.PARAMETER NewVersion
The version number of the new release in semver format.

.EXAMPLE
.\Publish-DevProxyToWinget.ps1 -OldVersion 0.19.0 -NewVersion 0.20.0
This example creates a new release of Dev Proxy.

.EXAMPLE
.\Publish-DevProxyToWinget.ps1 -OldVersion 0.19.0-beta.5 -NewVersion 0.20.0-beta.1
This example creates a new beta release of Dev Proxy.

.NOTES
Ensure that the GitHub CLI is installed and is authenticated with GitHub before running this script.
