Add resources and project ideas

If you navigate to resources folders, you might see some folders are kinda empty comparing with others. We need to fill them and add resources and project ideas in it to help folks get started in that particular tech stack.

Start by reviewing the repository's resources folders and comparing the sparsely populated folders with the others. Identify which technology stacks need coverage and define a manageable set of resources and project ideas for each selected folder. Done means the chosen folders contain useful, curated starting material.
