chore: remove JS community integrations

[Naomi Pentrel (npentrel)]

As we are sunsetting langchain community, we are removing associated integrations pages. Many important integrations have already moved into dedicated packages featured on our integrations page: https://docs.langchain.com/oss/python/integrations/providers/overview. Companies interested in maintaining an official integration can follow our contributor docs at https://docs.langchain.com/oss/python/contributing/integrations-langchain, create their own standalone package, and contact us to be featured on our integrations page: https://docs.langchain.com/oss/python/integrations/providers/overview.

❌ docs.json validation failed

This PR has issues with docs.json: either pages were removed without redirects, or some pages reference non-existent source files.

 The following pages were removed from docs.json without adding redirects:
  - oss/javascript/integrations/chat/bedrock

Please add a redirect for each removed page to the `redirects` array in docs.json.
Example: {"source": "/path/to/removed-page", "destination": "/path/to/new-location"}

should have a warning instead

[ccurme (ccurme)]

I'm not sure how important this page is. If it's reasonably important / people read it, then instead of an admonition here, I'd suggest we replace usage of WebBaseLoader with a short function as done here: https://github.com/langchain-ai/docs/pull/4058/changes

[Naomi Pentrel (npentrel)]

created a separate ticket, let's get this merged first

[ccurme (ccurme)]

why delete these? none of these are in langchain-community afaik

[Naomi Pentrel (npentrel)]

good catch

[ccurme (ccurme)]

A bunch of integrations got carved out of langchain community into standalone packages recently: https://github.com/langchain-ai/langchainjs/tree/main/libs/providers

It looks like the docs weren't updated. Ideally we update the docs, or at least for now spare the pages that are in the directory linked above.
