Enforce checkout with LF to fix Windows CI

[chezou]

Windows CI fails when parsing CSV with line breaks within a cell. This is due to the difference of line endings between CRLF vs LF, and test CSV parser implementation.

To mitigate this issue, tweak Windows CI to enforce git checkout with LF.

I found that root cause is this line: https://github.com/tabulapdf/tabula-java/blob/3c2af18f7c3daedafb6a4d33ab5f818cdc468d09/src/test/java/technology/tabula/UtilsForTesting.java#L86

but, I gave up to fix this since I can't understand original intention for it.
