Need to update the docs with 2 new functionalities in Caravan Docs. - A section for Wishbone and TL-UL in the User's Guide indicating that these two bus protcols can be used by user in their design [in this way](https://github.com/merledu/nucleusrv/blob/4c90ea871783ad0f870cf275f86c880a2f81f617/src/main/scala/components/Top.scala#L21-L22). - Addition of Adapters in the [User Guide](https://caravan.readthedocs.io/en/latest/user/index.html), that the user can also use complete Adapters for [Tilelink](https://github.com/merledu/caravan/blob/main/src/main/scala/caravan/bus/tilelink/TilelinkAdapter.scala) and [Wishbone](https://github.com/merledu/caravan/blob/main/src/main/scala/caravan/bus/wishbone/WishboneAdapter.scala) instead of [creating one manually with host and device](https://github.com/merledu/caravan/blob/6a0a861dc456bf8bd72a41740413af24dfcd3f95/src/main/scala/caravan/bus/tilelink/Harness.scala#L32-L33)
