docs redundant pages (#14774)

[ScaNN](https://python.langchain.com/docs/integrations/providers/scann)
and
[DynamoDB](https://python.langchain.com/docs/integrations/platforms/aws#aws-dynamodb)
pages in `providers` are redundant because we have those references in
the Google and AWS platform pages. It is confusing.
- I removed unnecessary pages, redirected files to new nams;
