UserWarning: Unknown distribution option: 'tests_require'

Nobody has claimed this yet.

- ROS Version: Humble

- OS Version: Ubuntu22.04

- Python Version: 3.10.12

- setuptools Version: 75.2.0

Hello, when I build this project from source, some warnings occurred.

Hers is the output of the command `colcon build`:
```
Starting >>> launch_system_modes
/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'
warnings.warn(msg)
--- stderr: launch_system_modes

/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'
warnings.warn(msg)
---
Finished <<< launch_system_modes [1.53s]

```

These warnings show the `tests_require` option is expired. But the `python` is the default package with ubuntu 22.04 and `setuptools` is installed by `pip`.

And then I use `colcon test` to test this project, there were also some warnings.

Here is the output about the command `colcon test`:
```
Starting >>> launch_system_modes

/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'
warnings.warn(msg)
--- stderr: launch_system_modes

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

Finished <<< launch_system_modes [0.72s]

```
It seems like that there were no python testing programs to run and no result file `pytest.xml` was generated in build directory.

Then I tried to modify the `setup.py` file in package `launch_system_modes` and replaced the option `tests_require` with `extras_require`.

Finally it can be built and test correctly.

Here is the modified content in `setpu.py` file:
```
tests_require=['pytest'], # remove
extras_require={
'test': ['pytest'],
}, # add
```

But there are some format errors after running `colcon test`. Here is the result:

[launch_system_modes.log](https://github.com/user-attachments/files/21450880/launch_system_modes.log)

Now the python and setuptools version are updated very quickly, could you tell me if it is necessary to replace the `tests_require` option to adapt to the current environment.

Thanks!

Start with setup.py in the launch_system_modes package and reproduce the reported colcon build and colcon test output using the stated ROS, Ubuntu, Python, and setuptools versions. Compare the current tests_require configuration with the reported extras_require change, then use launch_system_modes.log and the build directory to determine whether the warning, test execution, and pytest.xml output are resolved.
