refactor(i18n): new hook api (#7273)
# NEW HOOK API

`useI18n`: same as `useAFFiNEI18N`, with additional APIs

```ts
import { useI18n } from '@affine/i18n'

const i18n = useI18n()
i18n['hello world']() -> 你好世界
```

# NEW GLOBAL i18n Instance

`I18n`: use i18n capabilities outside of React

```ts
import { I18n } from '@affine/i18n'

I18n['hello world']() -> 你好世界
```

# NEW TYPES

`I18nKeys` -> all i18n keys

`I18nString` -> An i18n message (key&options)
transfer and store i18n text outside of React
```ts
const msg: I18nString = {
  key: 'helloworld',
  options: {
    arg1: '123'
  }
}

I18n.t(msg) -> 你好世界123
```

before:

```ts
registerCommand('open-page', {
  name: t('command.open-page')
  // ^- translation happens here,
})
```

after:

```ts
registerCommand('open-page', {
  name: { key: 'command.open-page' }
  // ^- store I18nString here, translate when the command render to UI
})
```

# i18n
## Usages
- Update missing translations into the base resources, a.k.a the `src/resources/en.json`
- Replace literal text with translation keys
```tsx
import { useI18n, LOCALES } from '@affine/i18n';
// src/resources/en.json
// {
// 'Text': 'some text',
// 'Switch to language': 'Switch to {{language}}', // <- you can interpolation by curly brackets
// };
const App = () => {
const i18n = useI18n();
const changeLanguage = (language: string) => {
i18n.changeLanguage(language);
};
return (
<div>
<div>{i18n['Workspace Settings']()}</div>
<>
{LOCALES.map(option => {
return (
<button
key={option.name}
onClick={() => {
changeLanguage(option.tag);
}}
>
{option.originalName}
</button>
);
})}
</>
</div>
);
};
```
## How the i18n workflow works?
- When the `src/resources/en.json`(base language) updated and merged to the develop branch, will trigger the `languages-sync` action.
- The `languages-sync` action will check the base language and add missing translations to the Tolgee platform.
- This way, partners from the community can update the translations.
## How to sync translations manually
- Set token as environment variable
```shell
export TOLGEE_API_KEY=tgpak_XXXXXXX
```
- Run the `sync-languages:check` to check all languages
- Run the `sync-languages` script to add new keys to the Tolgee platform
- Run the `download-resources` script to download the latest full-translation translation resources from the Tolgee platform
