Use lease_connection over deprecated connection for rails 8

[vprigent]

Call register_task as extending DatabaseTasks doesn't hold onto that

Fixes #352

This currently causes the rails db:prepare:with_data to run but silently fails to run the data migrations.

Weird is that rails db:drop db:prepare:with_data runs it fine...

There seems to be erratic issues with sqlite when running rails db:drop && rails db:prepare:with_data that isn't quite just relevant to data-migrate. It looks like somehow rails db:drop happens but the db files remain behind, cause db:prepare:with_data to still find the data_migration versions.

rails db:drop db:prepare:with_data seems to not cause the issue.

This worked fine with Rails 7.1 through to 8.0
Unfortunately lease_connection was only added recently and isn't available for older Rails versions.

I've faced some issues when I was doing drop-create-migrate in the past, but with a larger RDBMS. Probably not the best chain of commands to execute ever. So I guess it's alright
