Is your feature request related to a problem? Please describe.

When i use redoc-cli to build, i can't generate html with url under self signed cert

npx redoc-cli build  URL_WITH_SELF_SIGNED_CERT

This is the error message

Error: request to URL_WITH_SELF_SIGNED_CERT failed, reason: self signed certificate
    at BaseResolver.<anonymous> (/home/user/.npm/_npx/088c5868f11c5564/node_modules/redoc-cli/node_modules/@redocly/openapi-core/lib/resolve.js:117:23)

Describe the solution you'd like

simular to curl, a -k or --insecure options allow to bypass the cert check will be great

Thanks @jackykwan-eventx , this is a good suggestion.

Perhaps this could be an option in the per-API configuration?
