[IMP] tutorials/js_framework: retarget links to the current major branch

Commits pushed on the odoo/tutorials repository are not automatically
forward-ported, which makes it cumbersome to keep all SaaS branches up
to date.

Because of this, and because Odoo developers are very unlikely to follow
tutorials specific to a SaaS branch, links to odoo/tutorials now target
the current major branch, or master if applicable. SaaS branches have
also been deleted from the odoo/tutorials repository.
