feat(commands): add a command for a list of "good to know" items for job applications, particularly juniors

[mwskwong]

The list of items is open for discussion. Feel free to comment, add, update, or remove some of the items.

I added dedent for better DX. Please let me know if you prefer not to do this in this PR, or use dedent to all other commands at once.

PR Summary

• Inclusion of new package 'dedent'
  The team has included a new package titled 'dedent' in our list of software libraries. We've specifically opted for version 1.5.3, and this has been added to our primary reference files (package-lock.json and package.json), which are basically the 'table of contents' for our project.

• Utilization of 'dedent' in Command Features
  In the file src/features/commands.ts, which controls a variety of operational and functional commands, the 'dedent' package has been put to use. More specifically, we've added a new item to a certain list that uses some fancy text formatting. Help prompts, classification schemes, and message handling methods have all been defined for this new item.

Code-wise this seems good to me! Saw you ask for feedback in the channel, this is good to merge if there isn't any dissent there

@vcarl @ghardin137 @kristersd There seem to be some issues with the build pipeline. Could you have a look?

[vcarl]

Sorry @mwskwong hadn't seen this! That's a known issue (#216), I ignored it for a while cuz it was ~ just me contributing hehe. Has been more and more confusing so I killed the thing causing it 👍 tyty

[mwskwong]

@vcarl I see. I guess your side need to re-trigger the checks or force merge this PR then, since I don't have permission to do so.
