Download instructions for windows are not correct

[stanuku]

If you are using windows, please use the following command

bin/ingest-opennlp/download-models.bat

Windows uses backward slashes "" instead.
Also there is a path issue within the download-models.bat

call "%~dp0elasticsearch-cli.bat" ^ -> doesn't work (I had to hard code the path on my computer)

Thanks for the report!

Can you possibly open a PR to fix it? I do not have a windows installation to test at the moment.

@stanuku - I'm running into the same error. How were you able to hard code the new directory, and not have the file overridden? I am running the gradlew clean check command, and the download-models.bat file gets overridden, so it keeps failing whenever I build it.
