Cypress tests consitency

[curquiza]

When trying to update this package to be compatible with MeiliSearch v0.25.0, we had some issues with the cypress tests.
We noticed
Tests / cypress-run (cf this file) are not running the same cypress test as Pre-Release Tests / cypress-run (cf this file)

Tests / cypress-run

• runs using the Vue playground
• runs against a REMOTE MeiliSearch instance (https://integration-demos.meilisearch.com)

Pre-Release Tests / cypress-run

• runs using the React playground
• runs against a local MeiliSearch instance, downloaded in the CI that will fetch the latest RC

We should

• use the same playground to ensure consistency between the pre-release tests and the others.
• use a local MeiliSearch to run the Tests / cypress-run tests. This will avoid update the remote instance to make the tests be green

@bidoubiwa we need your insight before implementing this, you might know why it was done like this. Is there any constraint regarding what I suggest?

I totally agree! See #559
Tests are only done on the local react server. Tests on other environments where never really done so I removed them. Playgrounds are still running correctly !
