refactor: remove folder/workspace from vsCodeCliArgs (#4932)

* refactor: remove folder/workspace from vsCodeCliArgs

Since we handle this in the vscode.ts route, we no longer need to pass it to VS
Code as a CLI arg since it's deprecated on that side.

* feat(vscode): redirect to folder from cli

* Update src/node/routes/vscode.ts

* fixup!: share redirect block

* fixup!: mmove req.query.ew block into if

* fixup!: refactor vscode tests

* refactor: make vscode.ts logic easier to read

* fixup!: fix broken tests and clean up logic

* chore: upgrade vscode version

* fixup!: delete unnecessary if closed block

* Update src/node/routes/vscode.ts
