Broken integrations links in the docs

[franciscolourenco]

There are two instances of this hyperlink which don't have a corresponding section in the docs: https://segment.com/docs/connections/sources/catalog/libraries/website/javascript/#selecting-destinations-with-the-integrations-object

I suppose the correct link should be https://segment.com/docs/connections/sources/catalog/libraries/website/javascript/#managing-data-flow-with-the-integrations-object
