Make swagger download automatically select architecture

[AaronDewes]

Comprehensive Summary of your change

This does not work for all architectures, but at least amd64 and arm64. I could also add a switch statement, but ARM64 seems to be the most important arch to implement right now (#3505).

Issue being fixed

Helps towards #3505

Could you please contribute in the following repo to support Harbor in ARM:

Thanks

The container is always a Linux container, isn't it?

And https://github.com/goharbor/harbor-arm seems unmaintained.

In my opinion, a second repo for arm is unnecessary considering how small the changes for arm64 support would need to be (This PR + another 10 line patch).

So please reopen or reconsider this PR.
