Document.adoptedStyleSheets is no longer readonly

Document.adoptedStyleSheets is no longer readonly: https://developer.mozilla.org/en-US/docs/Web/API/Document/adoptedStyleSheets

In an earlier version of the specification, the array was not modifiable, so the only way to add new stylesheets was to assign a new array to adoptedStyleSheets.

This causes issues with newer typescript (I'm using 5.3) that is aware of this. For me, tsc --skipLibCheck false --incremental false was failing.

Here is the diff that solved my problem:
