automation: splitting the determining and publishing of the Git Tag

This is needed as a part of hashicorp/pandora#3601 since we're going to be publishing
multiple Go Modules at different paths - but the version number of each of them is going to be the same.

As such this PR splits the determining and publishing of the Git Tag - such that the existing update tooling
continues to work with minor changes (tracked in hashicorp/terraform-provider-azurerm#24602)
