A better new_project.sh (#5191)

* A better new_project.sh

* Fix docstrings

* Use single quotes for anything not shown to user

* Missed this docstring

* Simplify get_git_username()

Thanks @vomindoraan

* chmod +x

* Add docstring for print_error()

* Break up git username call into multiple lines

* Use with statement here

* Conform to PEP 8 even more

* Turn it back into a shell script

* chmod +x again

* Update docs to reflect new keyboard generator usage

* Tweak wording slightly

* Trim trailing whitespace

* Don't actually need to escape the newlines here

* As I suspected, you can pass shift a number

* Prepend ./ to match the other code block

* Minor syntax tweaks

* The username token has changed

* Replace name in the readme too

* Make some reasonable assumptions about the presence of Git

 Now that you have a working board, it's time to get things in their permanent positions. I've often used liberal amounts of hot glue to secure and insulate things, so if that's your style, start spreading that stuff like butter. Otherwise, double-sided tape is always an elegant solution, and electrical tape is a distant second. Due to the nature of these builds, a lot of this part is up to you and how you planned (or didn't plan) things out.

 ## Adding Your AVR Keyboard to QMK
 
-QMK has a number of features to simplify working with AVR keyboards. For most keyboards you don't have to write a single line of code. To get started run the `util/new_project.sh` script:

-```bash

+
+To start working on things, cd into keyboards/mycoolkb,

 This will create all the files needed to support your new keyboard, and populate the settings with default values. Now you just need to customize it for your keyboard.
