GHTeamBuilder#parentTeamId should accept a long

[MarcosCela]

Describe the bug

The identifier for a GHTeam returns a long, while the team builder accepts an int. This causes
a compile error if not handled.

To Reproduce

I detected this issue because while provisioning teams using the following snippet:

public void example(GHTeam parentTeam){
organization.createTeam(teamName)
                .privacy(Privacy.CLOSED)
                .parentTeamId(parentTeam.getId())  <-- Problematic!
                .description(description)
                .create();
}

The following compile error is raised:

java: incompatible types: possible lossy conversion from long to int

This is due to a recent change: fdcf74e where GHTeam
extends GHObject, which causes an inheritance of the GHObject#getId() that is returning a long,
instead of the previous version of GHTeam#getId() that was returning an int.

Expected behavior

We should be able to "chain" the creation of a team with a direct call without the need for type conversion.

Additional context
I think that this should be as easy as GHTeamBuilder accepting a long instead of an int:

- public GHTeamBuilder parentTeamId(int parentTeamId);
+ public GHTeamBuilder parentTeamId(long parentTeamId);

Thanks for catching this and the PR.
