Test multiple Go verions in integration-test

Do you think we should add older versions? According to our compatibility doc we support go1.19 and above so maybe we should add go1.19 as well.

That's going to be a bit harder. All of the project mod files require at least Go 1.23. We will not be able to compile the project with older versions.

To accomplish this type of testing we will need to update the integration tests to build the end-2-end test applications (i.e. nethttp, nethttp_custom) with different versions of Go.

Closing this as it is duplicating the verification that the project can be built with both versions of Go. A more comprehensive approach mentioned above is required instead.
