When calling `distrobox assemble create` I get warning from find about `-name` and `-wholename`

**Describe the bug**

When running `distrobox assemble create` I get this warning in the stderr:

```
find: pozor: ‘-name’ se porovnává pouze proti názvu souboru, avšak zadaný vzor obsahuje oddělovač adresáře (‘/’), tudíž výraz bude pokaždé vyhodnocen jako nepravdivý. Nemysleli jste ‘-wholename’?
```

Gemini says that it is the translation of the English warning message

```
"find: warning: ‘-name’ matches only the base of file names, so non-directories will never match the '-name' ‘/’ pattern. Did you mean ‘-wholename’?"
```

**To Reproduce**
I can just run `distrobox assemble create -n --file ~/.config/distrobox/distrobox.ini` (or even without the `-n` argument).

Unfortunately, the reproduction is unrealiable. So, for example, I am not able to collect proper `--verbose` log right now.

**Expected behavior**
No warning

**Logs**
Attach also the output of `podman logs` or `docker logs`, possibly with `--latest` flag
