Fix IndexOutOfBoundsException when running on mismatched Eclipse

Update `spring-javaformat-formatter-elcipse` so that all of
`org.eclipse.jdt` is shaded into `io.spring.javaformat.eclipse.jdt`.

This update ensures that the version of the AST parsing classes are
aligned with the version of the formatter. Prior to this commit the
misalignment would cause `IndexOutOfBounds` exceptions.

Fixes gh-288
