Revise BBS documentation to mention webhooks and give clearer instructions
Created by: mrnugget
This is just the first step. I plan on adding more docs about the webhook integration after today's sync with @eseliger.
But what this does is:
- Consistently name it
Sourcegraph Bitbucket Server plugin
instead of mixing that andSourcegraph native code intelligence plugin
- Mention the features of the plugin
- Give clearer and easy to find instructions on how to install and set it up
All of this can be improved and I will probably push to this PR.
