Fix GitLab CI buildx configuration for multi-arch builds

Browse source 
Fixed docker buildx errors in CI/CD pipeline:

1. Set DOCKER_TLS_CERTDIR to empty string to disable TLS
   (buildx with docker-in-docker doesn't work well with TLS certs)

2. Added fallback to reuse existing builder if creation fails
   (docker buildx create ... || docker buildx use ...)

This fixes the error:
'could not create a builder instance with TLS data loaded from environment'
