Describe the bug
When scanning files with CRLF terminated lines gitleaks will not detect secrets.

To Reproduce

• Create a new file and add a secret to it. Check that end of line sequence is set to LF first. In VSCode it's indicated in the bottom bar on the right hand side.
  Running a scan will detect the secret.
• Change end of line sequence to CRLF and save the file.
  Running a scan now will not return any wanings.

Expected behavior
Gitleaks should return warnings for files with CRLF.

Basic Info (please complete the following information):

• OS: Ubuntu 21.10
• Gitleaks Version: v8.2.5
