"Copy as k8s" doesn't work in Safari

What happened?

I noticed during working on https://github.com/kumahq/kuma-gui/pull/1873 that using the "Copy as k8s" copy functionality doesn't work in Safari.

Separately, I looked a little deeper into it an it looks to be due to the browser security features that don't let you perform copy actions without a user interaction.

In this instance, when the user clicks the button, we perform a HTTP request before using the response of that to write to the users clipboard, hence the write is not really a result of a user interaction, but more a successful HTTP response.

When I briefly read into it, it seems like the "user interaction" is bounded by a time period. Following that I could reliably get the copying to work by using a short setTimeout, but as soon as I took the timeout past ~999 the copying reliably stopped working, producing a browser error (which we currently swallow). Other browsers seem to be more lenient on this. Although the assumptions I've written here could be entirely wrong.
