Add github light

[steff456]

This PR is part of https://github.com/Quansight-Labs/jupyterlab-accessible-themes/issues/40

For adding a new theme a new directory is created with the following structure,

├── theme_name
│   ├── src
│   │   ├── index.ts
│   ├── style
│   │   ├── index.css
│   │   ├── variables.css
│   ├── package.json
│   ├── tsconfig.json
│   ├── README.md

To test the new theme please follow the instructions in the updated readme.

A JupyterLab instance will start in your browser and you can select the pitaya smoothie theme, by clicking Settings > Theme > Github Light in the main menu.

Some screenshots on how it looks right now,

New theme checklist:

• [x] New directory with new package
• [x] Update the setup.py to include the new package
• [x] Create a README.md inside the new package with information about the color palette and resources
• [x] Update main README.md with new theme

Also - does this theme need registering in the setup.py file like the previous theme added?

I think it does, but I'm not sure how it was working before 🤔

Also I tried to install the package locally following the instructions in the README and was faced with this error

$ pip install -e .

Though on closer inspection, I noticed the index.css file for both themes is quite different in terms of what is being changed (buttons, tabs and the such) is this intentional and/or is there a rationale behind this?

They are indeed different. The pitaya smoothie one I used the resources that are available in the repo, and trusted in the way that previous authors wanted to modify the interface. As I'm trying to get the github theme as close as I can to both the VScode extension and web interface, I needed to do some extra changes on how to color certain parts like buttons, tabs, etc.

My prediction is that the css will vary between themes depending on what I'm basing them on. So, for example the Github theme will change different things compared to the blinds or gotthard. But I would like to have the same css with color variants for each, so all the Github variants will share the same css (I'm testing how this looks with the dark colors right now).

There's infinite ways to change the colors of the UI, and I'm experimenting while creating each theme. But my goal is to reach a really similar look and feel with each theme.

Also I tried to install the package locally following the instructions in the README and was faced with this error

Can you try again? I just updated the instructions, you need to build the node package and then you will be able to do the pip command. Let me know if that works!

@trallard @gabalafou I already made the requested changes, please let me know if there's anything else this PR needs for merging
