Display Union of Literals as a Literal ( #14993 )
...
## Summary
Resolves #14988
Display union of Literals like other type checkers do.
With this change we lose the sorting behavior. And we show the types as
they appeared. So it's deterministic and tests should not be flaky.
This is similar to how Mypy [reveals the
type](https://mypy-play.net/?mypy=latest&python=3.12&gist=51ad03b153bfca3b940d5084345e230f ).
In some cases this makes it harder to know what is the order in revealed
type when writing tests but since it's consistent after the test fails
we know the order.
## Test Plan
I adjusted mdtests for this change. Basically merged the int and string
types of the unions.
In cases where we have types other than numbers and strings like this
[one](https://github.com/astral-sh/ruff/pull/14993/files#diff-ac50bce02b9f0ad4dc7d6b8e1046d60dad919ac52d0aeb253e5884f89ea42bfeL51 ).
We only group the strings and numbers as the issue suggsted.
```
def _(flag: bool, flag2: bool):
if flag:
f = 1
elif flag2:
f = "foo"
else:
def f() -> int:
return 1
# error: "Object of type `Literal[1, "foo", f]` is not callable (due to union elements Literal[1], Literal["foo"])"
# revealed: Unknown | int
reveal_type(f())
```
