Add missing `blur` event to `gr.Number`

[ExcellentAmericanEagle]

Describe the bug

The gr.Number component is missing the blur event, even thought it was added back in 2022 #2449 alongside gr.Textbox which has it.

In the changes of #2448 I noticed it almost fully added it, but it misses adding "blur" documentation to gr.Number:

# Textbox has it:
@document("change", "submit", "blur", "style")

# Number doesn't:
@document("change", "submit", "style")

It's also missing from the latest gr.Number Docs

Reproduction

import gradio as gr

number = gr.Number() 

# `blur` isn't a property of of `number`
number.blur()

Severity

Blocking usage of gradio

[ExcellentAmericanEagle]

IMO, I think there shouldn't be a special gr.Number component just for numeric inputs and instead rely on gr.Textbox but pass it type="number" (like <input> in JS)

Currently at its form gr.Number is like a degenerated version of gr.Textbox - it lacks properties gr.Textbox has like text_align, copy event, show_copy_button, autofocus etc.

I don't see a reason to maintain almost two similar components.
I suggest making gr.Number a subclass of gr.Textbox or make it instantiate a gr.Textbox behind the scenes

Made it:

import gradio as gr

with gr.Blocks() as demo:
    number_state = gr.State(5)

    def update_number_state(new_number: float):
        return new_number
    
    @gr.render(inputs=[number_state])
    def render_number(number_value):
        number = gr.Number(value=number_value)
        number.blur(fn=update_number_state, inputs=[number], outputs=[number_state])

        gr.Markdown(f"Your number is **{number_value}**")
    
demo.launch()

Will open a PR shortly
