treewide: switch to gomod and bump everything

This switches version resolution from fietsje to gomod and updates
all Go dependencies. It also bumps rules_go (required by gVisor) and
switches the Gazelle naming convention from go_default_xxx to the
standard Bazel convention of the default target having the package
name.

Since Kubernetes dropped upstream Bazel support and doesn't check in
all generated files I manually pregenerated the OpenAPI spec. This
should be fixed, but because of the already-huge scope of this CL
and the rebase complexity this is not in here.
