[vue-language-core] Nullish coalescing assignment throws in Node 14

[cuebit]

The following line throws SyntaxError: Unexpected token '??=' error in Node 14 since the target has been bumped to ES2021.

language-tools/packages/vue-language-core/src/generators/template.ts

Line 797 in 5a9f46d

localVars[varName] ??= 0;

Is Node 14 no longer supported? If so, where is this documented?

[johnsoncodehk]

We dropped Node 14 support (#2489), are there still use cases where it is necessary?

[cuebit]

Thanks for the reference, makes complete sense.

No, the use case is not trivial. I can work around it. Thanks so much!
