Similar to a86b731038, this adds a `regex`
option to `vim::Search` command to allow disabling regex search.
Release Notes:
- Added `regex` option to `vim::Search` command to allow disabling regex
search by default in the keymap. Example usage:
```yaml
{
"context": "VimControl && !menu",
"bindings": {
"/": ["vim::Search", { "regex": false }],
}
}
```
