fix: hack fix for contract tests on MacOS (#19965)

fixes #19802

Contract Tests are failing with missing symbols runtime error on `MacOS` after `golang` version was upgraded to 1.20
A simple hack fix such a case is to use `go 1.19` only to build the status-go library that is used specifically for these integration tests.
Its ugly but it works and unblocks devs from running tests locally.

- execute `make test-contract` on MacOS and it should not fail.

not needed since this impacts only the integration tests.

- macOS
