Describe the enhancement requested

The ADBC pages in the Arrow specifications docs need to be updated to refer to ADBC spec version 1.1.0:
https://github.com/apache/arrow/blob/main/docs/source/format/ADBC.rst
https://github.com/apache/arrow/tree/main/docs/source/format/ADBC

The content on these pages could also be pared down somewhat and replaced with links to ADBC docs pages such as https://arrow.apache.org/adbc/current/format/specification.html
