as const + satisfies works incorrect

[Komock]

Example - https://stackblitz.com/edit/stackblitz-starters-8zhuuy?file=types.ts,validate-schema.js.
Run npm run generate-schema in console.
Typescript compilation doesn't give any error but schema generation does:

Type 'readonly X[]' does not satisfy the expected type 'X[]'.
  The type 'readonly X[]' is 'readonly' and cannot be assigned to the mutable type 'X[]'.

In Typescript using satisfies removes readonly modifier but not in schema compilation
