d9ef83bf - [red-knot] Consistently rename BoolLiteral => BooleanLiteral (#13856)

[red-knot] Consistently rename BoolLiteral => BooleanLiteral (#13856) ## Summary - Consistent naming: `BoolLiteral` => `BooleanLiteral` (it's mainly the `Ty::BoolLiteral` variant that was renamed) I tripped over this a few times now, so I thought I'll smooth it out. - Add a new test case for `Literal[True] <: bool`, as suggested here: https://github.com/astral-sh/ruff/pull/13781#discussion_r1804922827
