Fix package.json merge inconsistency

A bad merge means that our repo has devDependencies for both `react-native-platform-override@^1.6.5`, and `react-native-platform-override@^1.6.4`. These resolve to the same dependency, even locally, so this would normally be pretty harmless.

Beachball, at a very close time, has started failing to publish packages to Verdaccio, in our PR environment. The state between npmjs, and GitHub is consistent, as verified by `beachball sync`. It shows trying to bump packages that no longer exist in our package,json versions. This can be locally reproed via `beachball bump --verbose` against the PR in #9491.

```
PS C:\Users\nickg\Desktop\react-native-windows> npx beachball bump --verbose
Checking for changes against "origin/main"
fetching latest from remotes "origin/main"
Your local repository already has change files for these packages:
  @office-iss/react-native-win32
  react-native-windows
...
@react-native-windows/virtualized-list needs to be bumped because react-native-platform-override ^1.6.4 -> ^1.6.5
```

Trying to publish based on bump info, we then see `ERROR: Attempting to bump to a version that already exists in the registry: @react-native-windows/virtualized-list@0.0.0-canary.29`

Testing to see if removing the dependency incosnsistency fixes the incorrectly determined packages.bump. This change would not be accepted by PR, so I am commiting directly.
