Fix debugOptimized DevSettingsActivity manifest (#57406)

Summary:
Fixes #57396.

`debugOptimized` builds still expose the React Native Dev Menu `Settings` item, but `DevSettingsActivity` was only declared in the `debug` manifest. This caused `Settings` to crash in `debugOptimized` with `ActivityNotFoundException`.

This adds a `debugOptimized` manifest matching the existing debug dev-support manifest, so `DevSettingsActivity` is declared for that build type.

[ANDROID] [FIXED] - Fix Dev Menu Settings crash in debugOptimized builds

Pull Request resolved: #57406

Test Plan:
Verified with RNTester debugOptimized:

``` sh
yarn install --frozen-lockfile
yarn start
./gradlew :packages:rn-tester:android:app:installDebugOptimized -PreactNativeArchitectures=arm64-v8a
```
then shake and tap `Settings`, confirm that Debug Settings opens instead of crashing.
