JosephandGitHub c3bf2a395a fix: preserve repeated search params in client page segment cache keys (#94863) ...

Fixes: #94821, #92787, #93104

Using `Object.fromEntries` on URLSearchParams, drops repeated keys.

```js
const s = '?foo=bar&foo=baz'
Object.fromEntries(new URLSearchParams(s)) // { foo: 'baz' }
```

There's already a function, `urlSearchParamsToParsedUrlQuery`, which
handles this case.

```js
urlSearchParamsToParsedUrlQuery(new URLSearchParams(s)) // { foo: ['bar', 'baz'] }
```

- [x] The e2e off one of the issue reports, I'll try to simplify it.
