[WEB-5059] feat: add page creation functionality to workspace seeding process (#7948)

* feat: add page creation functionality to workspace seeding process

- Implemented `create_pages` function to create pages for each project in the workspace based on data from `pages.json`.
- Integrated page creation into the `workspace_seed` task, ensuring pages are created alongside project issues.
- Added a new `pages.json` seed file containing initial page data and descriptions.

* fix: update page creation logic and seed data

- Set `is_global` to `False` for pages created in the `create_pages` function.
- Adjusted the project type check to be case-insensitive in the page creation logic.
- Added `id`, `project_id`, and `description_stripped` fields to the `pages.json` seed data for improved page initialization.
