Does not transform ||= "logical or assignment" operator

[cspotcode]

Describe the bug

swc does not transform the "logical or assignment" operator (||=)

Input code

I can reproduce this using swc's JS API:

const swc = require('@swc/core');
swc.transformSync(`a ||= b`, {});
swc.transformSync(`a ||= b`, {jsc: {target: 'es5'}});

In both cases the output is:

a ||= b;

Config

N/A

Expected behavior

The ||= operator is transformed into something similar to TS's output.

https://www.typescriptlang.org/play?target=8&ts=4.3.2#code/IYAgPmC8IEYNxA
TypeScript transforms a ||= b into a || (a = b)

Version
The version of @swc/core: 1.2.59
