Fix direction values in template for Go migrations

[ifraixedes]

Having a Go migration I realized that they don't work with this fork meanwhile they worked with the original repo; the go file generated doesn't compile.

I also found that strings.ToTitle doesn't return the wanted outcome meanwhile strings.Title does.

This PR fix the 2 issues.

Can anybody review the PR?
I need this issue solved, it's stopping our CI in some projects because we cannot run the Go migrations.

@ifraixedes I'm not sure if this repo is being maintained anymore but this fix exists in this version of the project https://github.com/steinbacher/goose/blob/master/migration_go.go

@zabawaba99 I could run that fork, using the same command that I use to run the migrations with this fork, I got

 environment variable.

@ifraixedes that's right, I forgot about some difference between the projects. You would need to alter your yaml configuration to use dsn instead of open.

Old:

driver: postgres
 open: user=liam dbname=tester sslmode=disable

Current:

driver: postgres
 dsn: user=liam dbname=tester sslmode=disable

@zabawaba99 thanks, I cannot take a look know, I may try the following days, we have to move forward with several things, so for now we disabled the CI

@zabawaba99 I wanted to confirm that your fork works.
Thanks
