feat: move templates into AFFiNE (#5750)

Related to https://github.com/toeverything/blocksuite/pull/6156

### Change
Move the edgeless templates to AFFiNE. All templates are stored as zip files. Run `node build-edgeless.mjs` in `@affine/templates` to generate JSON-format templates and importing script. The template will be generated automatically during building and dev (`yarn dev`).
