Removed trailing whitespace
Reasons for making this change
Aligns with Python style guidance PEP 8 explicitly advises avoiding trailing whitespace, noting that trailing whitespace is visually indistinguishable and can be confusing, especially when editors or tools auto-trim it. PEP 8
Matches common linting rules and CI expectations Popular Python linters and style tools such as pycodestyle/Flake8 (W291) and Ruff flag trailing whitespace as a violation, and many projects treat these warnings as errors in CI. Removing trailing whitespace from Python.gitignore aligns the template with those widely adopted rules.
Reduces noisy diffs caused by modern editors Editors like Visual Studio Code support files.trimTrailingWhitespace, which trims whitespace on save. When users enable this (often the default recommendation), the current Python.gitignore template results in unintended changes and noisy diffs as soon as the file is saved. Removing trailing whitespace avoids these spurious diffs and makes using the official template smoother.

These references together justify removing trailing whitespace as consistent with Python style, tooling, and typical editor behaviour.
