`execnet` missing in deltachat-rpc-client's pyproject.toml

[missytake]

• Operating System (Linux/Mac/Windows/iOS/Android): xubuntu 24.04
• Core Version: 2.23.0
• Client Version:

Expected behavior

I tried running the chatmail/relay tests with:

cd chatmaild
pipx run tox

And expected the tests to import deltachat-rpc-client's testplugin without problem.

Actual behavior

Instead I saw a ModuleNotFoundError, because execnet isn't installed. Since
d75a78d it is imported in deltachat-rpc-client's testplugin.py.

But execnet doesn't appear in https://github.com/chatmail/core/blob/main/deltachat-rpc-client/pyproject.toml, and is not automatically installed, so programs which import deltachat-rpc-client don't install it automatically either. I don't know whether it should be a dependency or a devDependency, but somehow we need to add it.

Steps to reproduce the problem

1. git clone github.com/chatmail/relay/
2. cd relay/chatmaild
3. pipx run tox

It is only needed for test plugin, and is installed as a dependency of pytest-xdist already if you install "dev" dependency-group, that's why the tests work.

I install it in chatmail/relay#750
