ci: removed installation unnecessary apt dependencies

[ErikBjare]

Turns out the step didn't run (the startsWith(os.runner, 'ubuntu') should have been startsWith(os.runner, 'linux')), but since things work fine without it we might as well drop it altogether.

Edit: I also added a CI badge to the README.

I was taking a look at this PR, and tried to do a fresh install of eeg-notebooks

Some packages might actually be necessary to run. Notice that the test github action does not actually run any tests. pip install -e . works fine on my system, but eegnb runexp does not.
So, the current PR is 'fine' in it's current form.
The real problem isn't the unnecessary apt dependencies, it's the lack of an initial test that might identify installation issues.

I am trying to install eeg-notebooks on a fresh ubuntu 20.04 image and am having issues that seem related to psychopy.

Based on the psychopy documentation for installing linux, it looks like there are at least two manual steps required for this to work on:

1. install wxPython
2. install a few debian packages

Debugging Info Below

The initial error I am receiving is:

(venv) ➜  eeg-notebooks git:(master) ✗ eegnb run_notebooks.py

If I install additional packages with pip install -r requirements.txt it installs two additional packages:

Installing collected packages: cryptography, pyOpenSSL
Successfully installed cryptography-3.2.1 pyOpenSSL-20.0.0

Then the following error:

I install pyo and pygame, but still receive an error

after installing that, we finally get to the wxpython error

dang.

[jnaulty]

installing wxPython worked ;)
I had to install gtk3: sudo apt install libgtk-3-dev
Then reinstalled wxPython: pip install --no-cache wxPython (this took about ~15 minutes on my computer to recompile everything with the gtk3 bindings).

[jnaulty]

Closing because #54 is in a state to merge and resolves issues related to building + testing eeg-notebooks on linux

[ErikBjare]

@jnaulty Good call, and nice work on #54!

I cherry-picked 2cc53f7 directly onto master.
