🛠️ Bug Fixes

[Line Chart Theme Initialization Issue](https://github.com/Thisal-D/ctkchart/issues/15)

A thank you to **[Bromson3105](https://github.com/Bromson3105)** for reporting and investigating the issue related to theme configuration for `CTkLineChart`. The problem occurred when the `ThemeManager` was initialized before creating chart widgets, resulting in the error:

`
Line Chart theme configure failed: 'CTkLineChart' object has no attribute '_CTkLineChart__y_axis_frame'
`

**Fix:**
The `ThemeManager` initialization has been updated to run *after* the chart object is created, resolving the issue.

**Steps to Update:**
To get the fix, update to the latest version by running:
bash
pip install --upgrade ctkchart
