Fix docker build - `apt-get install speedtest` failing

[bazzani]

When building the image I am seeing problems trying to install the speedtest package. This is fixed by using the current installation command from the speedtest website:

• https://www.speedtest.net/apps/cli
• RUN curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | bash RUN apt-get install -y speedtest

Hi @robinmanuelthiel would you be able to review this PR as it blocks us building the docker image?
