Let me explain more about this PR.

In this PR, I change the dependency from leetcode-cli to vsc-leetcode-cli, which is a forked privacy build of the leetcode-cli. This is due to that the latest version of leetcode-cli has some broken features and inactive for a long time. So I have to replace it with my forked version.

So far I have no plan to write a new cli tool to replace it. I'm very willing to merge back to the origin leetcode-cli when it becomes active again.

Using a forked version of leetcode-cli is a better choice I think, we can keep in sync with the upstream(leetcode-cli), and then fix known issues ASAP or customize the extra features we need.
