fix: add meilisearch as a dependency on lms-job

[Danyal-Faheem]

Running the Meilisearch init job when the platform is stopped would crash as the meilisearch container wouldn't be running and the endpoint could not be hit.

We add a dependency in the lms-job on meilisearch as the meilisearch init job is run inside the lms container.

I find it weird that we never caught this issue when we were running elasticsearch. What's the error stacktrace? And can you please add a changelog entry?

The error only occurs when running the meilisearch init job as we are trying to connect to the container. We didn't see this with elasticsearch as there was never an init job for elasticsearch.

Here's the stacktrace:

The above exception was the direct cause of the following exception:

I've added the changelog entry.

ES did not have an explicit init job if I remember correctly.
