Isssue generating declaration files with object containing keywords as property

TS playground does not have 4.8.2 yet, but this issue can happends in 4.8 beta:

https://www.typescriptlang.org/play?moduleResolution=99&target=99&jsx=0&module=199&ts=4.8.0-beta#code/C4TwDgpgBAMg9gYwIYBsIBEnCVAvFAJQgTgCcATAHgGdhSBLAOwHMAaKRiANwlID4AUKEhQAwnEY9SweMjTjGAM3rNKAFSgQAHsAiNy1WIlQYsOfLJOZsfPIWJkqAqFFoMWrZ1DUC+AbiFwaEt5CWVVDW1dfUMQ02w7OOskW3wiEgoaOiY2KAAFJGl6VHU+fwEBbTAyYCgmXVJFJARoAHEIGWM0agB5MGB6CWp1TR09AyM5eJSoAG8vFyQwMAAuKABXRgBrRjgAd0YAlxdyCCb1lGA1hSlOqYVw0qPjkiUVAH41uIeVUqgAHw2+jOTAg5GeLkYSAAthBPq5siwAgBfCpVGpQV60KDMDpxQz4EZRcaxLrTPgACnmxygSzAnhpUNhDOOp3OlzWbKQFzuJmoPzYC0xYRUa3W1F4+IFdlmyM8yLW7V53T6AyGpQAlNcJLdviKIqlbNTjqQOutSIwoFyeVL9SiAkA

The DTS result is wrong because default is a keyword:

export declare const getLocales: <T extends LocaleData>({ app, name, default, config, }: GetLocalesOptions<T>) => ConvertLocaleConfig<T>;

Meanwhile older ts versions work well:

https://www.typescriptlang.org/play?moduleResolution=99&target=99&jsx=0&module=199&ts=4.7.4#code/C4TwDgpgBAMg9gYwIYBsIBEnCVAvFAJQgTgCcATAHgGdhSBLAOwHMAaKRiANwlID4AUKEhQAwnEY9SweMjTjGAM3rNKAFSgQAHsAiNy1WIlQYsOfLJOZsfPIWJkqAqFFoMWrZ1DUC+AbiFwaEt5CWVVDW1dfUMQ02w7OOskW3wiEgoaOiY2KAAFJGl6VHU+fwEBbTAyYCgmXVJFJARoAHEIGWM0agB5MGB6CWp1TR09AyM5eJSoAG8vFyQwMAAuKABXRgBrRjgAd0YAlxdyCCb1lGA1hSlOqYVw0qPjkiUVAH41uIeVUqgAHw2+jOTAg5GeLkYSAAthBPq5siwAgBfCpVGpQV60KDMDpxQz4EZRcaxLrTPgACnmxygSzAnhpUNhDOOp3OlzWbKQFzuJmoPzYC0xYRUa3W1F4+IFdlmyM8yLW7V53T6AyGpQAlNcJLdviKIqlbNTjqQOutSIwoFyeVL9SiAkA

export declare const getLocales: <T extends LocaleData>({ app, name, default: defaultLocalesConfig, config: userLocalesConfig, }: GetLocalesOptions<T>) => ConvertLocaleConfig<T>;

I think this is a critial bug and should be fixed in 4.8.3 asap

Also I was curious:

1. why could this happends? Is related test cases missing? Maybe the team should check test cases and add some releated test into it.
2. When will you update your website? Hours passes after releasing 4.8 to stable, maybe the team can update ts playground faster, and that DOES help developers.

@MartinJohns So why thumbs down.

So you think this is a complicated snippet? Or it's normal for a project with 83.7k stars and 676 contributors should keep the website outdated days after new version? I have open source project too, 1 is probably ok if no one ever comes out the idea to add related test. But I don't think it's ok for 2.

I have the tendency to give the down thumb to issues ignoring the issue templates. Weird flex, I know.

Also, this sounds extremely entitled and rude:

When will you update your website? Hours passes after releasing 4.8 to stable, maybe the team can update ts playground faster, and that DOES help developers.

I did a bisect, and #41044 did change this, yes.

I agree this is a 4.8 patch candidate. cc @andrewbranch
