Fix links to vscode-language-dhall repository (#2118)

While the HTTP links properly redirect to the new repo, the git clone
command would checkout an old `master` branch. It took me a while to
figure out what went wrong 😅

 # Dhall language support in VSCode/ium
 
 The Dhall language integration consists of the following parts:
-- The VSCode/ium plugin "Dhall Language Support" *([vscode-language-dhall](https://github.com/PanAeon/vscode-language-dhall))* adds syntax highlighting for Dhall files.
-- The VSCode/ium plugin "Dhall LSP Server" *([vscode-dhall-lsp-server](https://github.com/PanAeon/vscode-dhall-lsp-server))* implements the LSP client – yes, there is a naming issue here – that communicates with the backend via the [LSP protocol](https://microsoft.github.io/language-server-protocol/specification) to provide advanced language features like error diagnostics or type information, etc.

 # Installation
@@ -23,7 +23,7 @@ The "official" releases can be installed as follows:
 2. Install the *typescript* compiler with `npm install -g typescript`. I recommend running `npm config set prefix '~/.local'` first to have npm install the executable in `~/.local/bin`; this avoids having to use *sudo* and polluting the rest of the system.
 2. Check out a copy of the vscode-dhall-lsp-server repository into the VSCode/ium extensions folder
    ```
-   git clone [email protected]:PanAeon/vscode-dhall-lsp-server.git ~/.vscode-oss/extensions/vscode-dhall-lsp-server
+   git clone [email protected]:dhall-lang/vscode-dhall-lsp-server.git ~/.vscode-oss/extensions/vscode-dhall-lsp-server
    ```
    (replace `~/.vscode-oss/` with `~/.vscode/` if you use VSCode instead of VSCodium).
 3. Run the remaining commands in the checked-out directory
