Use maintained nodejs18-debian12 base image

 - The nodejs distroless image was last updated 10 months ago and as
   such there are a number of high severity CVEs present in the last
   flyteconsole image that shipped v1.10.2

 - The existing base image is based on node v18, so for compatibility
   use the gcr.io/distroless/nodejs18-debian12 image, which is being
   actively maintained:
