we've forked this to get a newer upstream terraform go module.
we're running the nodejs version in production (see https://github.com/gynzy/pulumi-statuscake/releases/tag/v1.0.6)

main goal really was to triage the random provider errors and while we have achieved improvements there is still work to be done in that area upstream in the tf module (StatusCakeDev/terraform-provider-statuscake#195 and StatusCakeDev/statuscake-go#37).

but i wanted to offer this PR here in order to get this updated.

note: we're running the nodejs version and we've updated tested the nodejs version of this. thus NOT the go/python variants. we updated the ci/cd pipeline in order to get the node + go wrapping working (some changes we required, i.e. in the goreleaser syntax).

appreciate if this could be worked into main here
