Fix button in branch list, avoid unexpected page jump before restore branch actually done (#21562)

This patch:
- Use `<button>` replace anchor link `<a>` in **_Delete/Restore
Branch_** button to avoid unexpected page jump before restore branch
actually done.
- Also replace right side buttons with `<button>` in branch list, let
some screen readers know they are buttons.


## Before
click restore branch -> restore triggered -> page refreshed, but branch
status not update -> manually refresh page
