Merge #19495

19495: Rust: Update dependencies r=chrysn a=chrysn

### Contribution description

This updates both the RIOT-specific and generic dependencies of Rust examples and modules.

It also follows a deprecation from the G unit renaming originally done in https://github.com/RIOT-OS/RIOT/pull/19292.

### Testing procedure

* Green CI should do

### How to do similar PRs

Updating the RIOT-related dependencies (which here also updated bindgen because the dependency of riot-sys changed):

```
$ for x in **/Cargo.lock; do cargo update --manifest-path=${x%.lock}.toml --package riot-sys --package riot-wrappers; done
```

Updating everything (should never really be needed, b/c if something has a concrete dependency change it'd say so, but dependencies generally get better over time):

```
$ for x in **/Cargo.lock; do cargo update --manifest-path=${x%.lock}.toml; done
```

Creating the commit message:

```
$ git log --first-parent --format='%s (%b)' 9c29faf55d4c14d2d7f55f8df5059c52af4e5317..e4973a6ee88427f702dac41b3dce4fd6b6b9689e | sed 's/Merges: //' | sed 's/^/    * /'
```

git shortlog unfortunately doesn't show the merges the way I prefer linking them. The versions in the command line can be taken from `git diff --text` and looking for the riot-sys or riot-wrappers line, respectively.
