Steps to Reproduce:

Calling .path on WorkspaceFolder.uri returns the Windows drive letter “as is” (in my case, the drive letter is uppercase). For instance:

console.log(vscode.workspace.workspaceFolders[0].uri.path) 
// /D:/a/asciidoctor-vscode/asciidoctor-vscode/test-workspace

However, vscode.workspace.findFiles returns a list of URI with the Windows drive letter as lowercase. For instance:

console.log((await vscode.workspace.findFiles('**/antora.yml')).map((uri) => uri.path).join(', ')) 
// /d:/a/asciidoctor-vscode/asciidoctor-vscode/test-workspace/antora.yml
// /d:/a/asciidoctor-vscode/asciidoctor-vscode/test-workspace/cli/antora.yml

Windows is case-insensitive but I think it would be better to return normalized URIs (or at least return a consistent value across APIs)
