Fix incorrect `module.name_mapper` in template .flowconfig (#26330)

Summary:
Has explained in #26233, current template is incorrect & can create error, like having require() of png that are considered as `string` instead of `number. This can probably hide tons of similar mistakes.

The change in this PR should resolve the previous behavior (& for example, some places in previous version of the flowconfig have the full path like here https://github.com/facebook/react-native/blob/35300147ca66677f42e8544264be72ac0e9d1b45/template/_flowconfig#L61)

Closes #26233

## Changelog

```
[General] [Fixed] Fix incorrect `module.name_mapper` in template .flowconfig
```

Alternatively, message could be

```
[General] [Internal] Fix incorrect `module.name_mapper` in template .flowconfig
```
