LOG: [lldb-vscode] Update installation instructions (#68234)
lldb-vscode had installation instructions based on creating a folder
inside ~/.vscode/extensions, which no longer works. A different
installation mechanism is needed based on a VSCode command. More can be
read in the contents of this patch.
Closes https://github.com/llvm/llvm-project/issues/63655

# Installation for Visual Studio Code
-Installing the plug-in involves creating a directory in the `~/.vscode/extensions` folder and copying the package.json file that is in the same directory as this
-documentation into it, and copying to symlinking a lldb-vscode binary into
-the `bin` directory inside the plug-in directory.

-
-```
-$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
-$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
-$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
-$ cp /path/to/a/built/lldb-vscode .
-$ cp /path/to/a/built/liblldb.so .
+Installing the plug-in involves creating a directory in any location outside of
+`~/.vscode/extensions`. For example, `~/vscode-lldb` is a valid one. You'll also
+need a subfolder `bin`, e.g. `~/vscode-lldb/bin`. Then copy the `package.json`
+file that is in the same directory as this documentation into it, and symlink
+the `lldb-vscode` binary into the `bin` directory inside the plug-in directory.
+
+Finally, on VS Code, execute the command
+`Developer: Install Extension from Location` and pick the folder you just
+created, which would be `~/vscode-lldb` following the example above.

-It is important to note that the directory `~/.vscode/extensions` works for users logged in locally to the machine. If you are remoting into the box using Visual Studio Code's Remote plugins (SSH, WSL, Docker) it will look for extensions on `~/.vscode-server/extensions` only and you will not see your just installed lldb-vscode plug-in. If you want this plugin to be visible to remoting users, you will need to either repeat the process above for the `~/.vscode-server` folder or create a symbolic link from it to `~/.vscode/extensions`:
