Dangling reference to pip install -e . in episode 2.3

[sjvrijn]

In episode 2.3: Continuous Integration for Automated Testing, under the example .github/workflows/main.yml file there is a 'dangling' reference to "use python3 -m pip install -e as before", which is not actually listed anywhere until that point.

Once installed, we can use python3 -m pip install -e . as before to install our own package.

I'm guessing this sentence should just be removed from the paragraph?

Oh, that was probably mentioned before but then removed - we probably need to check if this is still needed and if yes, explain what the command does (otherwise remove that line). @steve-crouch what do you think?
