[Feature]: Change the Current Opened File in Workspace from `html` to `blade.php`

[Bakugo90]

Description

Implement a feature to change the extension of the currently opened file in the workspace from .html to .blade.php. This feature will ensure that only HTML files are converted to Blade templates.

Task

1. Utilize the VS Code API to check the extension of the currently opened file in the workspace.
2. If the file has a .html extension, proceed with the conversion to .blade.php.
3. If the file does not have a .html extension, display an appropriate message to the user.

Acceptance Criteria

• The extension should only convert files with a .html extension to .blade.php.
• If the currently opened file does not have a .html extension, an informative message should be displayed to the user.
• The implementation should use the VS Code API to determine the file extension.

Additional Context

This feature will enhance the robustness of the extension by preventing unintended file conversions and improving user experience.## Description
