Error code : 2 after update to 0.10.0 @intlify/unplugin-vue-i18n

### Reporting a bug?

For a translation like
```json
{
"address": "user{'@'}domain"
}
```

I get an error when running webpack build :
```sh
$ webpack --config webpack.config.js
[unplugin-vue-i18n] 2 (error code: 2) in /locales/en.json
target message: user{'@'}domain
target message path: address

1 | user{'@'}domain
| ^^^^^

[unplugin-vue-i18n] 2 (error code: 2) in /locales/fr.json
target message: utilisateur{'@'}domaine
target message path: address

1 | utilisateur{'@'}domaine
| ^^^^^^
