APT package name gets truncated if it contains a dot

I've tried out the new prerelease (`0.4.0-prerelease.2`), in a branch https://github.com/probe-rs/probe-rs/pull/1830.

It seems that the package name gets truncated if it contains a dot.
I've specified the libusb package like this:

```toml
libusb-1.0-0-dev = "*"
```

The result was that the workflow tried to install a `libusb-1` package.

I was able to fix this by putting the package name in quotes `"libusb-1.0-0-dev"`.

This seems to be a [TOML issue](https://toml.io/en/v1.0.0#keys), but maybe it could be detected somehow?

Start by reproducing the issue with the shown `libusb-1.0-0-dev = "*"` declaration, then read how APT package names are interpreted from the TOML configuration. The issue does not name files or tests. Done should mean a dotted package name is no longer silently truncated, or the unsupported syntax is clearly detected.
