wezterm: add confirm parameter to CloseCurrentTab

Browse Source 
When confirmation is enabled, a really basic overlay is
rendered over the top of the tab to request confirmation.

The default key assignment for CloseCurrentTab now
has confirmation enabled.

```lua
action=wezterm.action{CloseCurrentTab={confirm=true}}

action=wezterm.action{CloseCurrentTab={confirm=false}}
```
