3. Report an error "Can't install 'vscodevim.vim' extension because it is not compatible with the current version of VS Code (version 1.60.0)."

Notes

This issue can be reproduced in VS Code: No

Note: It could be installed if I downgrade code-server to 3.11.1 and fully operational after I upgrade to 3.12.0, so I think it just a fake alert.
Add Note: I tried code-server --install-extension vscodevim.vim and it perfectly work:

Installing extensions...
Installing extension 'vscodevim.vim'...
Extension 'vscodevim.vim' v1.21.8 was successfully installed.

It may be a frontend mistake.
