I don't get support sqlserver with the library

[vmasyagin]

Good afternoon. I'm trying to use your code as a library in the code. In file go.mod I write the dependency github.com/golang-migrate/migrate/v4 v4.15.2. Everything is regular, but only the dependency for postgres arrives, while others do not. I, in particular, need to work with sqlserver. How can I normally achieve this? Maybe I missed something in the documentation?
