Description

• Updates spec_version variable in variables.yml file for moonbase

I will create a separate PR to update the docs-test-suite repo re: runtime upgrade test

Did you double-check the links that use the moonbase.spec_version variable? Most of these links reference a specific line in the code that is subject to change as each runtime version is rolled out. So to keep our links pointing at the correct line of code, we need to double-check the links and update the lines. Usually there is like one or two places that always needs to be updated, so just want to make sure that wasn't missed
