fix(deps): Resolve installation conflict between gradio and spacy (typer)

[fumito072]

Hi there,

This PR fixes an installation failure caused by a dependency conflict.

The Problem

The project fails to install via pip install -e . due to incompatible requirements for the typer library:

1. gradio==5.44.1 (in pyproject.toml) requires typer>=0.12.
2. russian-text-stresser (a dependency) requires spacy==3.6.*.
3. spacy==3.6.* in turn requires typer<0.10.

The requirements typer>=0.12 and typer<0.10 are mutually exclusive, leading to a ResolutionImpossible error.

The Solution

I have downgraded gradio from 5.44.1 to 4.33.1 (the latest 4.x release).

Gradio version 4.x removed its direct dependency on typer, which successfully resolves this conflict. The installation now completes successfully.

Let me know if you'd like any changes!
