`libReplacement: true` lookup folder should be configurable (via `typeRoots` ?)

### 🔎 Search Terms

When `libReplacement: true` is used, for example
```
"libReplacement": true,
"lib": ["dom", "esnext"],
```
It is currently not possible to instruct the TS compiler to look for `@typescript/lib-dom/` in a custom folder, which makes it impossible to leverage `libReplacement: true` in setups where the folder does not reside in the parent chain (real-world scenario in the Chromium repository). For example adding something as follows has no effect.

```
"typeRoots": [
"./some/sibling/folder/node_modules/@typescript", <-- Does not work
"./some/sibling/folder/node_modules/@typescript/lib-dom" <-- Does not work either
],
```
Pasting `--traceResolution` output for reference.
```

======== Module name '@typescript/lib-dom' was not resolved. ========

Or if `typeRoots` is not the right way, there should be some way to customize where to look.

Let me know if you think a minimal repro is needed. Skipping for now as the above setup seems easy to reproduce.

### 🕗 Version & Regression Information

Reproducing on v 6.0.2. Did not try previous versions.

### 🙁 Actual behavior

No way exists to tell `tsc` where to locate the `@typescript/lib-dom/` folder.

### 🙂 Expected behavior

There should be a way tell `tsc` where to locate the `@typescript/lib-dom/` folder, similar to how this is done with `typeRoots` for types listed in `types`.

Start by reproducing the configuration with libReplacement, typeRoots, and --traceResolution, then trace how tsc resolves @typescript/lib-dom. Compare the lookup with typeRoots behavior and define a configuration path that works for sibling folders; done means the custom location resolves reliably and regression coverage verifies it.
