Describe the Bug

I noticed this warning when I installed Astro via pnpm install or pnpm update, I then investigated it and found that it was due to tsconfck being deprecated soon.

The original author is discontinuing the project dominikg/tsconfck#240

The author recommended switching to https://github.com/privatenumber/get-tsconfig, get-tsconfig might have some differences in behavior so it is worth investigating further, as far as I can tell the differences between both pacakges is minimal.

There is also a chance we can utilize rolldown built-in utilities for this vitejs/vite#21577

Doing my own research I think get-tsconfig is the best balance here, while avoiding potential future edge cases and/or behaviour drift. If we're fine with behaviour drift then the rolldown utility would be the most convinent solution here.

What's the expected result?

tbh using an alternative that doesn't output warnings.
