Great job on the PR. Thanks for your first DMC contribution 🎉

Just a couple tips:

• It's a good practice to create a branch in your cloned dmc repository for making changes, instead of using the master branch. No need to update anything for this PR—just a note for future contributions.

• In the PR description, If you include:

closes #424

then the associated issue will automatically close when the PR is merged, and it will indicate there's an active PR linked to that issue.

Additions

• To chip away at improve Python docstrings #421, please add a one sentence description to the Radio and RadioGroup component. Can you change this line so the description reads something like:

For Radio

/** Wrapper for input type radio. */

Then for the RadioGroup

/** The RadioGroup gives user radio inputs to allow only one selection from a small set of options. */

Feel free to change it if you have any better descritpions

• Need to add a Changlog entry. starting on the second line, add:

# Unreleased

### Added
- Added `disabled` prop to `Radio`  #425  by @namakshenas 

---

Tests
No need to add at test when it's just a prop passed to the Mantine component.

Here's another example that will be good for the docs - a disabled RadioGroup

App on Pycafe

import dash_mantine_components as dmc
from dash import Dash, dcc, _dash_renderer

_dash_renderer._set_react_version("18.2.0")

app = Dash(external_stylesheets=dmc.styles.ALL)

component = dmc.RadioGroup(
    children=dmc.Group([
        dmc.Radio("A", disabled=True, value="A"),
        dmc.Radio("B", disabled=True, value="B"),
        dmc.Radio("C", disabled=True, value="C")
    ]),
    value="A",
    label="Select an item",
    m="lg"
)



app.layout = dmc.MantineProvider([component])


if __name__ == "__main__":
    app.run(debug=True)
