project: fix keyboard interruption for scripts

[blankoworld]

We often run poetry run server. And we stop it with Ctrl+C. This
generally gives a keyboard interruption signal that stops the processus.

But this is broken: the processus is already runned!

This commit fixes the issue by sending again the interruption signal to
the runned script.

Why are you opening this PR?

The poetry run server often let invenio server and celery worker running (after Ctrl+C keyboard interruption). When we launch it again: it returns an error about "Port already addressed".

This PR changes the behaviour by sending an interruption signal to launched script when using a keyboard interruption command.

How to test?

• Launch poetry run server
• Wait few seconds (for server to be launched)
• Interrupt the server with [Ctrl] + [C] command
• ps aux|grep invenio should not return any launched process
• ps aux |grep celery should do the same (except if you have other invenio instances launched)

In the commit message, change "processus" by "process". And "But this is broken: the processus is already runned!" by "But this is broken: the process are still running!", if I got it right.
