Support LUA 5.5

[kalin-toshev]

Thanks for creating this great extension! With the latest update to LUA 5.5, though we hit an issue with a 'const' variable (for loop variable modified inside the loop body). I suggest the following fix (which I also have applied locally on the compiled version (VSCode extension) and it seems to work ok) -

diff --git a/debugger/sourcemap.ts b/debugger/sourcemap.ts
index 96da419..3fbce5f 100644
--- a/debugger/sourcemap.ts
+++ b/debugger/sourcemap.ts

             const scriptRootsStr = os.getenv(scriptRootsEnv);
             if (scriptRootsStr) {
                 for (let [path] of scriptRootsStr.gmatch("[^;]+")) {
-                    path = Path.format(path) + Path.separator;
-                    table.insert(scriptRoots, path);
+                    table.insert(scriptRoots, Path.format(path) + Path.separator);
                 }
             }
         }

Without this, we are getting an error -

...
	....local-lua-debugger-vscode-0.3.3/debugger/lldebugger.lua:331: attempt to assign to const variable 'path'
stack traceback:
	[C]: in ?
...

It would be great if this is fixed, so we won't need to apply fix manually after installing the extension in VSCode.

I fixed it and there is already a PR.
