demo: git-first e2e (schema-node-label marker)

[luvkapur]

E2E verification flow 1 (git-first). Should be adopted into a bit.cloud lane by bit-adopt-pr.yml, then synced by bit-sync.yml. Will be closed without merging.

[github-actions]

bit-git-sync could not reconcile this branch automatically: branch has commits but its .bitmap records no state for this lane; cannot tell which side is newer

To resolve locally:
git fetch origin && git checkout 'demo-e2e-git-first'
bit lane import 'teambit.api-reference/demo-e2e-git-first'

resolve conflicts, commit the result, then:

git push origin 'demo-e2e-git-first'

Remove the bit-sync-conflict label to resume syncing.
