Format spm-scripts.md after applying review suggestions

The GitHub suggestion commits reflowed prose past the print width, padded a
table cell, and left trailing whitespace on a heading — prettier --list-different
flags the file, which is what the lint job runs.

 | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
 | `name`    | The target's name and its header prefix. A valid Swift identifier, not [reserved](#names-react-native-reserves), and not already taken by another module or an autolinked library.                                                                                                                                |
 | `path`    | The module's directory, relative to the app root.                                                                                                                                                                                                                                                                 |
-| `exclude` | Paths inside `path` to keep out of the target, like a podspec's `exclude_files`. It also supports directories with a trailing `/`.                                                                                                                                                                                            |

 | `sources` | Glob allowlist replacing automatic discovery, like a podspec's `source_files`. Without it, every `.h/.m/.mm/.c/.cpp/.swift` file under `path` is compiled, minus `exclude` and the directories the autolinker always skips (`android/`, `test/`, `tests/`, `__tests__/`, `__mocks__/`, `jest/`, `node_modules/`). |
 
 Names must be unique because wrapper directories are keyed by name: two entries
 resolving to one name — or an entry matching an autolinked library — would share
 a directory, and the losing module would silently not be built. So a clash fails
 the build with a rename instruction instead.

 `spm.modules` is read from the app's own `react-native.config.js` only — entries
 in a dependency's config are ignored, so a library cannot declare its native
