…o `arrow.recordBatch` (camelCase) (#37223)

### Rationale for this change

As @ kou suggested in #37215 (comment), it makes sense to rename `arrow.recordbatch` (all lowercase) to `arrow.recordBatch` (camelCase).

`recordBatch` is the first "two-word" function in the top-level `arrow.*` package, so it makes sense to establish a clear camelCase standard for "multi-word" functions in the MATLAB interface at this point.

One part of the rationale motivating this change is that other language bindings follow a similar pattern (e.g. `pyarrow.record_batch` instead of `pyarrow.recordbatch`).

### What changes are included in this PR?

1. Renamed `arrow.recordbatch` (all lowercase) to `arrow.recordBatch` (camelCase).
2. Updated documentation and tests to reflect `arrow.recordbatch` being renamed to `arrow.recordBatch`.

### Are these changes tested?

Yes.

1. All existing MATLAB tests have been updated to use the new name `arrow.recordbatch` and are passing on my Debian 11 machine.

### Are there any user-facing changes?

Yes.

**This PR includes breaking changes to public APIs.**

The public facing API `arrow.recordbatch` has been renamed to `arrow.recordBatch`. Since the MATLAB interface is still "pre 1.0", we don't expect this change to have a significant impact.

…upport for new MATLAB APIs (e.g. `RecordBatch`, `Field`, `Schema`, etc.) (apache#37215)

### Rationale for this change

Over the last few months, a number of new user-facing APIs have been added or changed in the MATLAB Interface.

## Examples:

### Construction Functions

- `arrow.array`
- `arrow.field`
- `arrow.schema`
- `arrow.recordbatch`
- `arrow.boolean`, `arrow.string`, `arrow.timestamp`, etc. (type construction functions)

### Classes

- `arrow.type.Field`
- `arrow.tabular.Schema`
- `arrow.tabular.RecordBatch`
- `arrow.array.StringArray`
- `arrow.array.TimestampArray`

### Indexing Methods

- `arrow.tabular.Schema.field(i)`
- `arrow.tabular.RecordBatch.column(i)`

### Static Construction Methods

- `arrow.tabular.RecordBatch.fromArrays(a1, ..., aN)`
- `arrow.array.StringArray.fromMATLAB(a)`

This pull request updates the [`README.md` for the MATLAB Interface](https://github.com/apache/arrow/blob/main/matlab/README.md) to reflect these changes.

### What changes are included in this PR?

Updated MATLAB `README.md`:

1. Updated **Status** section to mention support for new Arrow types and functionality.
2. Added usage examples for `Type, `Field`, `Schema`, and `RecordBatch`.
3. Updated Feather v1 usage examples to illustrate support for types like `String` and `Boolean`.

### Are these changes tested?

N/A.

This is purely a documentation change. I manually reviewed the visual rendering of the `README.md` Markdown on GitHub.

### Are there any user-facing changes?

Yes.

1. The MATLAB `README.md` now includes more usage examples which illustrate how to use the MATLAB interface.

### Future Directions

1. Add comprehensive documentation for all classes and methods, including supported input argument types and name-value pairs.
2. Add more detailed information on future development plans and development status to the `README.md`.
3. Add a table of contents to the MATLAB `README.md`.
4. Keep the `README.md` up to date more proactively.

### Notes

1. Thank you @ sgilmore10 for your help with this pull request!
2. My apologies in advance if this is too much documentation content to review at once. We will focus on being more incremental about keeping the MATLAB documentation up to date in the future.
3. apache#37211 also involves updating the MATLAB `README.md`, so there is a chance we may need to rebase before merging these changes in.
