Force lsif-java version

Previously, the lsif-java version was inferred by `coursier launch`.
This caused problems because Coursier didn't always pick up the latest
release, even a few days after the release was out.  Now, we explicitly
specify the version to ensure that we use the latest release is picked
up.
