Upgrade meilisearch dependency (fix jest tests not supporting ES modules)

[bradenmacdonald]

Upgrading our meilisearch client package is blocked:

This seems to be blocked on upgrading from fetch-mock-jest to @fetch-mock/jest, which in turn is blocked on ESM support in Jest.

frontend-app-authoring/node_modules/@fetch-mock/jest/dist/esm/index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import { FetchMock, defaultFetchMockConfig, } from 'fetch-mock';
                                                                                      ^^^^^^

    SyntaxError: Cannot use import statement outside a module

One solution could be to replace jest with Node's built in test runner, at least for those tests.
