Subject: [PATCH] Increase nested update limit to 100 (#31061)

We're seeing the limit hit in some tests after enabling sibling
prerendering. Let's bump the limit so we can run more tests and gather
more signal on the changes. When we understand the scope of the problem
we can determine whether we need to change how the updates are counted
in prerenders and/or fix specific areas of product code.
