Pass showProgress to fetchOptions

[riseshia]

Fix: #1453

#1067 seems not to pass showProgress to fetchOptions, which makes any fetch call handled without --progress Confirmed works correctly with default / explicitly given show-progress option, here is test result https://github.com/riseshia/actions-playground/actions/runs/6078541181

I don't add test for this, because I couldn't find proper place for this case(most test are unit testing, but this problem is from "passing" arg) 🤔 any suggestion for adding test is welcome. ;)
