chore(docs): remove code of conduct

[JonZeolla]

Contributor Comments

Unfortunately we need to remove the code of conduct because they do not reliably respond to our link checker, which is important to us for maintenance. It is causing a large number of build failures. For example:

✗ [ERR] https://www.contributor-covenant.org/version/3/0/ | Failed: Network error: Connection reset by peer (os error 104)

This has happened over numerous weeks, and most recently here and over a month ago here
