Core file web/core/lib/Drupal/Core/FileTransfer/Local.php is being ignored due to .gitignore config

[halisonfernandes]

Describe the bug
Due to the default BLT's .gitignore file, the file web/core/lib/Drupal/Core/FileTransfer/Local.php isn't being versioned during the artifact:deploy command.

To Reproduce
Steps to reproduce the behavior, ideally starting from a fresh install of BLT:

1. Run composer create-project acquia/drupal-recommended-project --no-interaction
2. Run composer require acquia/blt
3. Configure the git section of your blt.yml
4. Run the artifact:deploy command

Expected behavior
All core files be versioned on the artifact.
