fix(specs): add getVersion parameter to getSettings

[millotp]

🧭 What and Why

🎟 JIRA Ticket: CR-9310

Add the getVersion query parameter to getSettings.
This was removed in https://github.com/algolia/doc/pull/7793, but is still useful for the Dashboard.

Original description of this parameter:

#### Backward compatibility

Synonyms were originally set via the index settings,
and a [Get settings](#get-settings) call would return all synonyms as part of the settings JSON data.

This behavior is still available to maintain backward compatibility.
If you don't want to include synonyms in your settings, add `getVersion=2` to your request as a query parameter:

`GET /1/indexes/{indexName}/settings?getVersion=2`

Until you switch to this new Synonyms API, you can still manage your synonyms via the index settings.
