Connecting to Weaviate issue using the local runner

[mrchtr]

We identified a bug in the indexing pipeline, which appears to be confined to a specific docker and linux version. To address this issue, when encountering a similar problem, follow these steps to resolve the bug:

When running the index_weaviate component with the local runner, there may be issues connecting to a local weaviate instance. To resolve this, note that we typically use http://host.docker.internal to determine the correct address of the database. However, in the specific setup where the issue arises, the host name is not recognised in the operating system.

In such cases, a workaround is to use the IP address 172.17.0.1 directly instead of relying on http://host.docker.internal to ensure successful connectivity.
