v3.0.0

This is a major release.

Breaking

• Minimum node v18
• Removes .redirect('back'), adds .back(fallback_url) @fl0w #1115
• For .redirect(), don't render redirect values in anchor ref ff25eb4
• req.origin should display the origin header if it exists, not the current hostname #1008. origin now aligns with the Origin header as used in CORS.
• .body=<json> should not overwrite type if type already json #1120
• Remove special ENOENT support #1861 - this is a big change and will require any file servers to adapt to this change for handling 404s / files not found
• Removes generator deprecation messages. Generators are no longer supported. Koa no longer asserts if generators are used.
  Set content-length: 0 if body is explicitly set to null @ognjenjevremovic #1528
