chore: bump to use go1.23

[AvitalTamir]

Hey, thanks for the PR! This seems to have broken the docker build:

#14 [builder  7/11] RUN go mod download
#14 0.397 go: github.com/avitaltamir/cyphernetes@v0.0.0-00010101000000-000000000000: module ./cyphernetes/ requires go >= 1.23.0 (running go 1.22.7; GOTOOLCHAIN=local)
#14 ERROR: process "/bin/sh -c go mod download" did not complete successfully: exit code: 1

If I understand correctly go 1.23 isn't available on the builder image? See the workflow output for more context.
