Release notes for 489

Luau constraint resolver can now refine properties of tables and classes.

Luau linter will start warning about duplicate locals and function arguments, e.g.

function obj:method(self, arg) -- here self is declared twice, implicitly and explicitly

unpack and table.unpack are now ~2x faster than before when used in a variadic context

Added support for Japanese, Spanish, and Portuguese languages to Studio

Fixed a memory explosion when type-checking generic methods.

Fixed a bug where the Script Editor formatter would incorrectly format multi-line conditions in 'if', 'elseif', and 'while' blocks.

Fixed a bug where Script Editor "Format On Paste" did not trigger when using paste menu button or right-click option.

Breakpoint Red marker circle position fix in relation to code.

The red breakpoint circle was drawn a few pixels too high and with smaller font sizes it was hard to see which line it belonged to. This change addresses this and now the circle lines up with the code line.

Fixed a bug that the TeachingCallouts still show when studio is minimized on Mac machines.
