New release needed to keep Krew up to date

[sterchelen]

Hi,
The latest krew release of kubectl-trace uses the v0.1.2 tag. This version has some inconsistencies:

1. In the Makefile, bpftrace version is set to v0.11.1 whereas in the Dockerfile it is set to v0.13.0 which is overridden by the Makefile variable.
   

   kubectl-trace/Makefile

   Line 29 in fd68b1c

   BPFTRACEVERSION ?= "v0.11.1"

   
   

   kubectl-trace/build/Dockerfile.tracerunner

   Line 1 in fd68b1c

   ARG bpftraceversion=v0.13.0

   
   Also the new version of bpftrace helps to fix this error

/bpftrace/include/clang_workarounds.h:14:10: fatal error: 'linux/types.h' file not found  

2. The image name set for the run traces still uses the old one kubectl-trace-bpftrace (new image name introduced in b41eb65)
   --imagename string Custom image for the tracerunner (default "quay.io/iovisor/kubectl-trace-bpftrace:fd68b1c1bf614a7213c9834673eb8813c809b036")

Thx 🙇🏼‍♂️.
