Fix/indentation on docs/get details/dapps/pyteal/index

[PabloLION]

The indentation in python is critical. I made some fix on the python codeblocks.
Remove: Dollar signs used before commands without showing output by markdown-lintMD014

Also after pip3 install -r requirements.txt the awesome-page is throwing some error. Please check.(should I create a new issue?)

  File "/opt/homebrew/lib/python3.10/site-packages/mkdocs_awesome_pages_plugin/plugin.py", line 9, in <module>
    from .meta import DuplicateRestItemError, MetaNavRestItem, RestItemList
  File "/opt/homebrew/lib/python3.10/site-packages/mkdocs_awesome_pages_plugin/meta.py", line 78, in <module>
    class RestItemList(collections.Iterable):
AttributeError: module 'collections' has no attribute 'Iterable'

I edited the line before fetch. The trailing whitespace caused the conflict
