Description

Main changes:

• format all files with prettier.
  Included files are:
  • everything in src
  • everything in server
  • some of the files located at the root directory (excluding yaml and markdown files), refer .prettierignore file to see excluded files: https://github.com/Fredkiss3/pangolin/blob/chore/fix-formatting/.prettierignore

Other changes:

• Added a job that checks that all files in are formatted correctly with prettier
• Added a job to run formatting accross the whole repo: npm run format
• Added .vscode/settings.json with some default options: setting prettier as the default formatter, and formatting on save
• Added .vscode/extensions.json with recommendations for new contributors recommending them to install prettier extension if not installed

@Fredkiss3 because of the merge conflicts as we get ready for this next release could you redo this PR or adjust it so that we are not formatting all of the files but you just include your changes for the npm run command and other vscode defaults? Then we will format once things are all merged up outside of a PR.
