fix(707): do not throw if the record-pattern contains dims

[clementdessoude]

What changed with this PR:

This piece of code was failing as the java-parser tried to parse String otherName, String[] otherContent as a variable declaration list instead of component pattern list

I added backtrack lookahead which fixed the issue but will see if we can avoid it completely.

// Input
public class Foo {
  public void bar() {
    if (!(obj instanceof Project(String otherName, String[] otherContent))) {
      return false;
    }
  }
}
