feat(vscode-web): use VS Code code CLI instead of VS Code code-server

[Ricky-Hao]

Hi,
The current VSCode Web module directly uses code-server to start a VSCode Web instance.
However, I noticed that the current VSCode Web only stores user credentials (e.g., GitHub authentication) in in-memory storage.

After investigating the VSCode source code, I discovered that VSCode Web requires a key from the /mint-key endpoint.
In Coder's code-server, the /mint-key endpoint is implemented.
However, in the official VSCode version, the /mint-key functionality is only available in the VSCode CLI (code binary).

To enable credential persistence, we need to use code serve-web to start a VSCode Web instance instead of the current code-server serve-local.

In this PR, I updated the process to use code serve-web to start a VSCode Web instance.
Most of the features from the old code-server are supported, except for the following two:

• OFFLINE
• USE_CACHE

I did not remove these variables from the .tf files to maintain compatibility.

@matifali this would be a good opportunity to use the new individual version tag structure when releasing.

Yes, if this lands, it should go as 2.0.0 for vscode-web. @bcpeinhardt can you take care of this?

Hi @Ricky-Hao, Sorry for not coming to this earlier. We were sorting versions for the modules, and as this module changes stuff significantly while Aldo breaks a few existing =g use cases, We needed that to land this in.

Can you update the README.md to reflect the changes? Specifically the ones which are o more supported.

I would also like @michaelbrewer to review as he has contributed to this module in past.

Hi @Ricky-Hao, why can we not support these two features with VS Code's code serve-web CLI?

Hi @matifali, sorry for the delayed response.
Since I’m not using these two features in my workspace, I’m not sure what they are supposed to do.

I think the difference here is that code serve-web also manages downloading the code-server binary, and we do not know if we can make it use an existing binary. IF we can somehow instruct it to use an already downloaded code-server binary, it should work with OFFLINE and USE_CACHED modes.
