update vscode extension create from example document

[brianignacio5]

Description

This pull request updates the VS Code Extension setup instructions in the ESP-ADF documentation to reflect recent changes in configuration and workflow. The most important changes clarify how to set the ESP-ADF path and update the process for creating new projects from examples.

Documentation and workflow updates:

• Updated instructions for setting the ESP-ADF path: users should now set the path using the idf.customExtraVars setting with ADF_PATH as the key, instead of the previous idf.espAdfPath or idf.espAdfPathWin settings.
• Revised the process for creating new projects: users now use the new project command, select the ESP-IDF version, and choose ESP-ADF examples if configured, with additional configuration options for the new project (directory, name, etc.).
