Refine MR unit tests and contribution guide

Changed the name of the unit tests CI job to accuratly reflect
that both AMD64 and ARM64 tests are executed.

Modified the contribution guide to specify that contributors
should work inside their own fork of the project.

 Some contributions might introduce changes that are incompatible with other existing nodes. In this case it is recommended to also set a development network *Guide Coming Soon*.
 
 Once you have added your new function or addressed a bug, test it locally to ensure it's working as expected. If needed, test your work in a development network with more than one node based on your code. Once you're satisfied your code works as intended and does not introduce negative results or new bugs, follow the merge requests section below to submit your work for maintainer review.

 ## Contributions Without Writing Code
 There are numerous ways you can contribute to the growth and success of the Veilid project without writing code:
 
+ - If you want to submit merge requests, begin by [forking] the project and checking out a new local branch. Name your new branch in a way that describes the work being done. This is referred to as a [feature branch].
  - Submit bugs as well as feature/enhancement requests. Letting us know you found a bug, have an idea for a new feature, or see a way we can enhance existing features is just as important and useful as writing the code related to those things. Send us detailed information about your issue or idea:
  	- Features/Enhancements: Describe your idea. If you're able to, sketch out a diagram or mock-up.
  	- Bugs: Please be sure to include the expected behavior, the observed behavior, and steps to reproduce the problem. Please be descriptive about the environment you've installed your node or application into.
