Powershell export (AUD-5758)

[Dennis40816]

Description

When using PowerShell to execute export.bat, the environment variable cannot be correctly set and exported to the current terminal. In September 2024, ESP-IDF introduced export.ps1 for PowerShell users. If ESP-ADF could also provide an export.ps1 script, it would greatly enhance the convenience for PowerShell users when setting up ESP-ADF.

Therefore, the following changes were made in this PR:

• Added export.ps1, which internally calls the export.ps1 from ESP-IDF.
• Modified docs\en\get-started\index.rst.

Screenshots

• using export.bat in PowerShell failed to properly set the environment variables, resulting in idf.py not being found
  
• using export.ps1 in PowerShell allows the environment variables to be set correctly, making idf.py accessible
