Ignore RUSTSEC-2024-0436 (#2562)

cargo deny reports:

```
ID: RUSTSEC-2024-0436
Advisory: https://rustsec.org/advisories/RUSTSEC-2024-0436
The creator of the crate `paste` has stated in the [`README.md`](https://github.com/dtolnay/paste/blob/master/README.md)
that this project is not longer maintained as well as archived the repository
Announcement: https://github.com/dtolnay/paste
Solution: No safe upgrade is available!
paste v1.0.15
└── ratatui v0.29.0
    ├── gitui v0.27.0
    └── tui-textarea v0.7.0
        └── gitui v0.27.0 (*)
```

In #2554 the decision was made
to ignore this advisory, as ratatui already has removed paste in
ratatui/ratatui#1713 and we are just waiting for
an upstream release.
