Add a snippet for the `if __name__ == '__main__':` block

We have all sorts of useful snippets in our extension, but I’ve noticed that we have not added one for the ubiquitous block:

if __name__ == '__main__':

Proposal to add the snippet with the type-ahead identifier __main__.

Acceptance Criteria:

1. Open a new editor window
2. Create a new file helloworld.py
3. Add the following code:

1|  import sys
2|  
3|  def hello_world():
4|      print('Hi there!')
5|      print(f'Python version {sys.version_info}')
6|  
7|

1. On line 7, begin type __main

Expected Result

Popup with a snippet for the dunder name equals dunder main appears. Pressing Enter will accept the snippet and insert code such as:

6|
7|  if __name__ == '__main__':
8|      $
9|

…where the $ is where the cursor is left such that the user can add whatever call(s) are necessary.

EDIT: Acceptance criteria altered to ensure cursor is placed optimally.

I personally just want:

if __name__ == "__main__":
    ${1}

Or whatever is required to have VS Code start the cursor indented in the if block.

Instead of pass that’s where the cursor should be placed.
