Create GitHub actions to test any code before merging

[upkarlidder]

Background on the problem the feature will solve/improved user experience

Add GitHub Actions to test and build new code pushed to a branch or committed to a pull request. Code that passes all the steps in the GitHub action can be merged in the repository.

Describe the solution you'd like

A GitHub action runs whenever code is committed to any branch or PR is made to the main branch for each of the following components:

• website folder
• mobile folder
• backend folder

Refer to a similar action that was implemented for the UI folder in Five Fifths Voter project.

Each action will

• install dependencies
• build for production
• run all tests
• linting with prettier. Discuss with the team on what linter to use.

Tasks

• Ensure install, build and lint steps run locally on your system
• Read more about GitHub actions
• Create an action for each folder. You can read more JavaScript build actions here.
• Commit and push your GitHub action code.
• Go to the Actions tab to see if it worked.

Acceptance Criteria

GitHub action runs for every new code commit and PR.

FYI @demilolu

Hi, I would like to work on this issue

[demilolu]

@arianahl go for it!

@demilolu the pull request adds the git actions requested. A few things I would like to point out:

1. backend and website don't have tests so I left that line commented out
2. backend and mobile don't have lint configured so I left that line commented out
3. website has lint but it is misconfigured and gives many errors when running

Are these known issues?

[demilolu]

@arianahl
I think 1 and 2 are, but I'm not sure about 3.

@upkarlidder @Jamstew2 insight here?

[upkarlidder]

For 3, are you able to fix the errors @arianahl. That would be ideal.

@upkarlidder If no one is working on the website part of the code I can give it go. Otherwise they would get a horrible merge on their hands.
Also a way to make it less intrusive is to change the current lint rule for parentheses: instead of having them on the next line leave them in the same line as most of the code already does. Actually this is only a problem in the index.js script. The rest of the files do follow allman style.
I can also go ahead and turn it on for the other two folders (different PR?).

It sounds good to me. @Jamstew2 and team can you please provide some guidance as well?
