[MEDIUM] RootlessKit update entry inconsistent with established pattern

This entry uses parentheses and no hyperlink:

- Update RootlessKit (3.0.0). [moby/moby#52319](...)

All other dependency update entries in this file follow this pattern (e.g. the 29.2.0 entry):

- Update RootlessKit to [v2.3.6](https://github.com/rootless-containers/rootlesskit/releases/tag/v2.3.6). [moby/moby#51757](...)

Suggested fix:

- Update RootlessKit to [v3.0.0](https://github.com/rootless-containers/rootlesskit/releases/tag/v3.0.0). [moby/moby#52319](https://github.com/moby/moby/pull/52319)

LGTM

we need a follow-up to update the example versions in Hugo, and to update the API version matrix.
