+.SYNOPSIS
+    Retrieves the download URL for the latest release of a GitHub repository.
+
+.DESCRIPTION
+    The Get-GitHubRelease function retrieves the download URL for the latest release of a GitHub repository. It uses the GitHub API to fetch the release information and matches the specified regex pattern to find the download URL.
+
+.PARAMETER repo
+    Specifies the GitHub repository in the format "owner/repo".
+
+.PARAMETER path
+    Specifies the local file path where the downloaded file will be saved.
+
+.PARAMETER match
+    Specifies the regex pattern used to match the desired download URL.
+
+.EXAMPLE
+    Get-GitHubRelease -repo "Microsoft/PowerShell" -path "C:\Downloads" -match ".*\.zip"
+
+    This example retrieves the download URL for the latest release of the "Microsoft/PowerShell" repository and saves the downloaded file to the "C:\Downloads" directory. It matches the download URL that ends with ".zip".
+
+.NOTES
+    - This function requires an internet connection to access the GitHub API.
+    - If the specified regex pattern does not match any download URL in the release information, the function will try to find the download URL without using the "latest" release.
+    - If no download URL is found, the function will try to get the tarball URL.
+    - If the tarball URL is also not found, an error will be displayed and the function will exit.
