feat: add weave documenation to ingestion pipeline

[parambharat]

In this PR we did two things.

1. Add weave documentation to the data ingestion pipeline
2. Remove Ja's documentation from the ingestion

We choose to remove JA documentation due to the following reasons:

1. In the new chat pipeline - the response synthesis module is instructed to respond in the user's query language. i.e. even if the context is in English, as long as the query is in JA the response will be in JA
2. The JA documentation is now moved to a new location the Docodile repository. The last two ingestions didn't ingest any JA docs due to this change, but the JA responses in JA Slack have still been working.
3. Additionally, new languages such as Kr have been introduced. Indexing each language is just storing redundant information in the vectorstore.
4. Since we use multi-lingual embedding search based on the query language, we can retrieve the information for questions in other languages even if the documentation is in English and the query is in other languages.
