Rework delete org and rename org UI (#34762)

# What's the problem of the original implementation

Renaming organization will mix with organization's information change
make the operation difficult to keep consistent.

This PR created a danger zone like what's repository setting. It also
moved organization's `rename` and `delete` operations to this zone. The
original updating repository will not change the name any more.

This is also a step to extract the `updaterepository` function
completely.
