State of Some Integrations

[TaMaN2031A]

Hello!
I tried to use MarqoDocumentStore and LanceDBDocumentStore. The first one is really broken; even the import statements return errors. I opened the repo, and it hadn't been updated in two years. A lot of haystack code in the repo seems to be old; tests don't start; many errors when running the linter. The second has an issue that will be addressed in the next version of LanceDB. Currently, writing data into this document store doesn't work.
Should these integrations stay in the documentation of haystack while not working?
