Rename repos

[rowanmanning]

After a Slack discussion the other day, I think we all agree that we should rename some of the repos:

• [x] ci to pa11y-ci
• [x] dashboard to pa11y-dashboard
• [x] lint-config to pa11y-lint-config
• [x] reporter-1.0-json to pa11y-reporter-1.0-json
• [x] webservice-client-node to pa11y-webservice-client-node
• [x] webservice to pa11y-webservice

All done 👍
