• I've included steps to reproduce the bug.

Describe the bug

According to this issue kubernetes-sigs/kubebuilder#2311 links using https://go.kubebuilder.io/dl/* should be avoided, they are redirects in the end to github.

This snippet in .gitpod.Dockerfile:8 would avoid the failure:

RUN curl -L https://github.com/kubernetes-sigs/kubebuilder/releases/download/v2.3.1/kubebuilder_2.3.1_$(go env GOOS)_$(go env GOARCH).tar.gz | \
    tar -xz -C /tmp/ && mv /tmp/kubebuilder_2.3.1_$(go env GOOS)_$(go env GOARCH) /usr/local/kubebuilder

To Reproduce

Start a new gitpod environment

Expected behavior
The gitpod environment should not fail
