An incorrectly formatted go.mod can permanently prevent the report card from refreshing

[Arzumify]

If a go.mod contains an invalid module path, by accident or otherwise, the go report card will successfully fetch on initial scanning, but will fail on all subsequent attempts due to attempting to use the potentially incorrect module path stated in the go.mod and will not fetch the new go.mod.

Suggestions to fix this:

1. Using named tags can fix this, as it would have to re-fetch the actual git repository to find the tag
2. Using the @master system pkg.go.dev has for a complete re-fetch could also work, as it'd allow the broken go.mod to be replaced
3. Allowing the removal of repositories can help, as a complete removal and re-initialization of the repository would fix the problem

I'd be happy to make a PR if no progress is made on this.
