fix: fails to generate declarationMaps

[2wheeh]

resolves #259

I found that #259 happens after 284c77f.

I just restored this change from the latest (63321c2),
which makes it generate .map files for .d.ts files well (checked on bac2a7d).

and It seems #254 is not reproduced 🤔(checked on b041a4c).

This reverts the fix of 284c77f, refer #254.

and It seems #254 is not reproduced 🤔(checked on b041a4c).

After building, useWakeLock.d.ts was not generated, and error TS4078 for useWakeLock.ts in the console.

@qmhc It seems this error TS4078 occurred because of typescript version. (not because of this revert)
With typescript @5.1.6, error TS4078 doesn't appear and useWakeLock.d.ts is generated. (d70bd45)

error TS4078 appears on #254's reproduction codes as well with typescript @5.0.4.

@2wheeh Nice job!

The reason I encountered this issue because I used the link protocol locally, and the TypeScript version was based on the vite-dts-plugin project.

Thanks for taking the time.
