Workspace cannot import sample project in proxied environment on OCP 4.7

Environment

OCP 4.7 cluster
Codeready Workspaces deployed by crwctl in proxied environment

Steps to reproduce
1. Install CRW  with next properties in custom-resources:

• nonProxyHosts: 'non-proxy-host'
• proxyPort: '3128'
• proxyURL: 'proxy-url'

2. Create and start workspace from any devfile.

Expected behavior:
The workspace ready to work with sample project imported successfully.

Observed behavior:
There is 'Couldn't import' error notification

This issue only for OCP 4.7. On OCP 3.11 it works as expected.

    If try to get sample zip file in proxy container(like "wget https://devfile-registry-crw-crwctl-with-proxy.apps.ocp311.crw-qe.com") it returns "ERROR: cannot verify devfile-registry-crw-crwctl-with-proxy.apps.ocp311.crw-qe.com's certificate" error. With `--no-check-certificate` works as expected. It looks like proxy certificate problem but this issue not reproduces on OCP 3.11 and worked well before on OCP 4.7 in previous CRW 2.7 version.
