[MM-62293]: Remove Elasticsearch from translation strings (#29728)

We cannot simply use Elasticsearch any more because
we support Opensearch as well.

Therefore changing Elasticsearch to just say Search.

Note: There are still some cases where Elasticsearch
is used. That is intentional and necessary.

```release-note
NONE
```
