docs: update Docker build commands to specify platform as linux/amd64 (#6977)

### What problem does this PR solve?

Considering the ragflow_deps image is only available for `linux/amd64`
platform, if we try to run the docker build commands in ,macOS for
instance, without the platform flag, we get an error due to the
different platform. Specifying the platform in the docker build command
fixes this issue.
