deps: fix CRLF in text file not present in upstream

`deps/v8/third_party/jinja2/LICENSE` is not in upstream v8,
and contains CRLF, which is in conflict with `deps/v8/.gitattributes`
which sets all text files to use LF.
This has caused failures in CI workers with older versions of Git.
This patch manually fixes up the file to use LF to resolve
the conflict.

The file has already been fixed in upstream jinja2,
which is pull into our repo when we update V8 so it should
be fixed the next time we update V8.
