feat: add codespace docs

[jdegand]

Added some notes about how someone can use GitHub codespaces to run the project and tackle challenges or make a PR.

I looked into adding a .devcontainer/devcontainer.json file to upgrade the features and node version of the codespace ( initial codespace starts with node 20 and some other basic features already installed) .

GitHub link for basic devcontainer info if you are unfamiliar.

The codespace installation fails during the automatically run installation process. User needs to run npm ci to correctly install.

This is why I added a note about how the initial install from Codespaces will fail. This may be preventable with a .devcontainer.json file and a Dockerfile may be necessary to have npm ci run automatically. Still looking more into this.

I suggest you try out a quick codespace experience and if you have problems, I could add more directions to the readme.

The codespace doesn't have immediate access to user's clipboard. Self-explanatory.

When you serve any project, a box will come up and user can click that to view the app running. It uses port forwarding. I didn't add a comment for this.

Nice, I had planned to explore codespace but I never had the time to do it, so I'm glad you took the time. I will try to follow your guideline.

I don't have time this week but I will do it next week. Thanks a lot

I changed the directions. Apparently, the issues I had installing the codespace were temporary glitches. It just installed perfectly with and without installing the optional VS Code plugins.

It would be best if you added a screenshot (as my username would be visible) for the modal with the codespace options (so it is not as zoomed in).

I added a link for a Github Skills tutorial and I think this is sufficient.
