Sorbet error when setting `host` config to `nil` in local development

The gem raising on local dev with a passed nil into T.must?
When the HOST env var is set where the gem reads, but that env var doesn't contain a protocol, so the gem raises here. For us it's failing on this concern from shopify_app . We can hack around it for now by explicitly setting the host , but it looks like either the gem needs to be updated to support local dev, or dev needs to be updated to include a protocol in the HOST env var?

Expected behavior

host config works without requiring protocol scheme. Maybe setting a default?

Actual behavior

The gem raising on local dev with a passed nil into T.must?

Steps to reproduce the problem

1. Include FrameAncestor in one of your controller
2. Set HOST env var as www.example.com without http or https

Debug logs

// Paste any relevant logs here

Start in lib/shopify_api/context.rb at the HOST handling around lines 62 and 177, then inspect the linked shopify_app FrameAncestor concern to follow how the value is used. Reproduce with HOST set to www.example.com without a protocol; done means the host configuration works without requiring a protocol scheme, with the intended behavior confirmed.
