Rename repository to dragonfly

[gaius-qi]

Rename our repository from Dragonfly2 to dragonfly to better align with our project naming conventions and to avoid any potential confusion. This change will help us maintain consistency across our project repositories and improve the overall clarity of our project structure.

Github will redirect https://github.com/dragonflyoss/Dragonfly2/ to https://github.com/dragonflyoss/dragonfly/.

Change repository to dragonfly:

• Rename repository.
• dragonfly: https://github.com/dragonflyoss/Dragonfly
• CNCF Landscape: https://github.com/cncf/landscape
• d7y.io: https://github.com/dragonflyoss/d7y.io
