reveal_type(x) where x: Tuple[int, ...] doesn't show "..." #9522

Bug Report

Using reveal_type() on a variable whose type is a variable-length tuple shows misleading output.

While it's different from the output for a fixed-length tuple (which shows Tuple[builtins.int]), it doesn't clearly indicate that the type is variable-length.

Note that with PEP 585 accepted, eventually we'll have to use builtins.tuple (or, I'd recomment, plain tuple) for both situations.

To Reproduce

from typing import Tuple
a: Tuple[int, ...]
reveal_type(a)

Expected Behavior

t.py:3: note: Revealed type is 'builtins.tuple[builtins.int, ...]'

or

t.py:3: note: Revealed type is 'Tuple[builtins.int, ...]'

Actual Behavior

t.py:3: note: Revealed type is 'builtins.tuple[builtins.int]'
