Update issue template/s.

Hey 👋

The issue template is using deprecated configuration/location/etc.
It also instructs reporting stuff related to old studio only.

Hey @igalklebanov 👋 Turns out main had no issue templates at all anymore — which partly explains the recent run of empty spam issues. #1556 adds fresh GitHub issue forms: a bug form with required distribution/database/version fields, a feature form, blank issues disabled, and contact links redirecting CLI/ORM problems to prisma/prisma and questions to Discord.
