Paul Lorenz 1c122af490 Rewrite channel/v4 imports to channel/v5. For #3983
- moves the channel dependency to channel/v5 v5.0.10 and sdk-golang to v1.9.0 in the root and zititest modules
- mechanically rewrites every channel/v4 import path to channel/v5

This is the import-path-only step; the API-level changes the switch requires land in the following commit. This commit does not build on its own.
