Drop maintenance banner

The project is operational again, so the not-actively-maintained banner in the README is no longer accurate. This also updates the project board link to the correct URL.

Part of #174.

-> [!WARNING]\
-> **This project is no longer actively maintained.** It may receive security updates, but we are no longer making major changes or improvements. EDGI no longer makes active use of this toolset and it is hard to re-deploy in other contexts.

-> - Looking for tools to monitor websites? Check out our [Awesome Website Change Monitoring](https://github.com/edgi-govdata-archiving/awesome-website-change-monitoring) document or [issue #18](https://github.com/edgi-govdata-archiving/web-monitoring/issues/18), which discusses similar projects. *(This project is most useful if monitoring several thousand pages in bulk, but in most cases, other existing tools will solve your needs faster and cheaper.)*
