feat: Add rebrand CI/CD workflows to main branch

- Add 72 rebrand workflow files (polkadot→pezkuwi, substrate→bizinikiwi, cumulus→pezcumulus)
- Add GitHub actions, issue templates, and configs
- Removed unnecessary workflows (fork-sync, gitspiegel, upstream-tracker, sync-templates, backport)
- Renamed zombienet test files to match new naming convention

+Generate the PrDoc for a Pull Request with a specific number, audience and bump level.

+It downloads and parses the patch from the GitHub API to opulate the prdoc with all modified crates.
+This will delete any prdoc that already exists for the PR if `--force` is passed.
+
+Usage:
+	python generate-prdoc.py --pr 1234 --audience node_dev --bump patch
