SPIRE initContainer with wait-for-it image needs to be updated for more CPU arches

Description

Also comment seems lost, have we confirmed it runs on arm64 and amd64v1?

This issue to to verify the above comment to confirm if the image cgr.dev/chainguard/wait-for-it@sha256:ecb58e3a2ffbdb732bb9049987e06eaf826d945410e167f31d6ffe28fab259f4 is working for both arm64 and arm64v1.

In the worst case scenario, we should find one alternative image and update respective value in helm chart.

I tested it out on my test server running on KVM:

root@qemu-cpu:/home/maartje# docker run cgr.dev/chainguard/wait-for-it@sha256:ecb58e3a2ffbdb732bb9049987e06eaf826d945410e167f31d6ffe28fab259f4
