[Maximiliano Sandoval]

otherwise:

```
warning: unclosed HTML tag `uid`
   --> proxmox-file-restore/src/main.rs:686:63
    |
686 | /// "www-data", so we use a custom one in /run/proxmox-backup/<uid> instead.
    |                                                               ^^^^^
    |
    = note: `#[warn(rustdoc::invalid_html_tags)]` on by default
```
