[bug#44988] [PATCH] gnu: vdirsyncer: Use a more recent version of python-requests-toolbelt.

Hi,

Yeah, sorry, I should have included the error message!

```
$ guix package -i poetry
The following package will be installed:
   poetry 1.1.4

guix package: error: profile contains conflicting entries for 
python-requests-toolbelt
guix package: error:   first entry: python-requests-toolbelt@0.9.1 
/gnu/store/gqx0ssh217cczj3fi88k5545mcb8cn80-python-requests-toolbelt-0.9.1
guix package: error:    ... propagated from poetry@1.1.4
guix package: error:   second entry: python-requests-toolbelt@0.8.0 
/gnu/store/9pgb39jybc823cbr0ajqp93cxnh2pn4m-python-requests-toolbelt-0.8.0
guix package: error:    ... propagated from vdirsyncer@0.16.8
hint: Try upgrading both `poetry' and `vdirsyncer', or remove one of them from 
the profile.
```

Yes it does! Thanks… but I'm still struggling with the why and when
of package versions! But, as it is related to my questions in
"Poetry upgrade and related packages", I'll elaborate there!
