in evil-insert mode, alt+number will switch workspace

### What did you expect to happen?

In evil-insert, I accidentally pressed `alt+number` when the completion candidates are not popping up, and the editor switch to another workspace, this is a very common situation when editing with company-mode and I think this should not happen if you are trying to edit something. Can these shortcuts be more useful in evil-insert?

### What actually happened?

in evil-insert mode, alt+number will switch workspace.

### Describe your attempts to resolve the issue

I directly disabled the keybinding (alt + number) when in evil-insert.

### Steps to reproduce

1. open emacs
2. select the workspace and switch to (current in 2nd workspace)
3. press 'i' to enter the evil-insert
4. press 'alt + 1', the editor will switch to 1st workspace
