[api-extractor] Error parsing tsconfig.json content: Unknown compiler option 'isolatedDeclarations'

[dubzzz]

Summary

api-extractor does not support the newly added isolatedDeclaration flag in tsconfig files.

Repro steps

Simply add the flag isolatedDeclaration to either true or false in a tsconfig file and run api-extractor.

Expected result: Should not throw about unrecognized flag

Actual result: Throws "Error parsing tsconfig.json content: Unknown compiler option 'isolatedDeclarations'"

Details

From my investigation, it seems that the fix would be to bump the dependency to typescript to 5.5+. But I prefer having your go if any before opening any PR or waiting for yours.
