Updates to ZEP0001

[MSanKeys963]

Hi everyone! 👋🏻

I've added a few changes to the ZEP0001. They are:

• Update ZEP0001 status to Accepted
• Add redirect from draft_zeps → accepted_zeps
• Add contributors list to ZEP0001

  I've gone through all the issues and PRs related to ZEP0001 and included the names of everyone who participated in the discussions and helped us finalise the specification. Please feel free to add names if I missed any.

Please have a look and let me know your thoughts.

Preview can be seen here: https://zeps--43.org.readthedocs.build/en/43/accepted/ZEP0001.html
