Add tdarr_autoscan to Tools and Integrations page

[hollanbm]

I was browsing the website for documentation, when I stumbled across the Tools and Integrations section.

I created tdarr_autoscan to notify tdarr of new additions. I had seen tdarr_inform, and it looked more complex than I would have liked, so I decided to create something as simple as possible.

It works by using curl, to send a request directly to the /scan-files endpoint. All of the params are set as environment variables.
