Fix the indentation size in code snippets

[gr1seo]

Use the same indentation size (4 spaces) for python code snippets, and remove the misplaced newline.

How did you discover this? Did you use some tool? Seems like adjusting spaces in random files.

I found missing indentation in the Utilities section under Finding Application Folders. After fixing it, I rechecked the docs using these regexes:

^\.\. click\:(?:example|run)\:\:\n{1,2}^(?: {1,3}| {5,7}| {9,11}| {13,15})[\w@]
^```python\n{1,2}^ {1,}[\w@] (added after an additional recheck following your comment, second commit 😅)
^(?:```python|\:caption\:.*\.py)\n{1,2}^(?: {1,3}| {5,7}| {9,11}| {13,15})[\w@]
^ *(?:class|def|with|for|while|if|elif|else).*?\:\n{1,2}(?: {0,3}| {5,7}| {9,11}| {13,15})[\w@]

I also reviewed the files with visible spaces enabled. The fix was done manually, without any tools, just the IDE’s find functionality.
