create exception for .bat files in check_eol

[ngonzalez-ccdc]

• Create an exception for .bat files when checking EOL in a non auto crlf environment (linux)
• I think if core.autocrlf in the git config is true and the commit hook is run on a windows machine it will automatically perform the conversion of files specified in .gitattributes. However in the pipeline this is run in a linux machine and it checks all new and modified files for CRLF line endings and fails if it finds any (including .bat).
