Link commit author to related Github account

[fbiville]

Currently, despite using what I think is the right email of @neo4j-oss-build, Github does not link the commit author to the account.

See for instance: neo4j-graph-examples/network-management@8936c49.

The configuration is done in CI:

sandbox-code-updater/.github/workflows/CI.yml

Lines 46 to 48 in 7a77fa1

	run: |
	git config --global user.name "Sandbox 🤖"
	git config --global user.email ${{ secrets.EMAIL }}
