Support for PowerPC `ppc64le` architecture

Is your feature request related to a problem? Please describe. I tried building the qdrant for ppc64le architecutre using the Dockerfile provided in the repo. But i was getting error at the last step.

# Relative order of `ARG` and `RUN` commands in the Dockerfile matters.
#
# If you pass a different `ARG` to `docker build`, it would invalidate Docker layer cache
# for the next steps. (E.g., the following steps may depend on a new `ARG` value, so Docker would
# have to re-execute them instead of using a cached layer from a previous run.)
#
# Steps in this stage are ordered in a way that should maximize Docker layer cache utilization,
# so, please, don't reorder them without prior consideration. 🥲
