Revert incorrect copyright attribution for non-contributed files

- In commit b3facaa6bb, the copyright header was
  updated to include "Citron Homebrew Project" across multiple files, regardless
  of whether any contributions were made.

- This commit removes the incorrect attribution and reverts the copyright header
  to its previous state.

- Copyright attribution should only be added when meaningful contributions have
  been made to the file.

- This commit ensures proper compliance with copyright standards and maintains
  correct attribution to the respective contributors.

- Special thanks to Tachi for pointing out the need for these corrections and
  ensuring that proper attribution practices are followed.
