Fix OpenOCD rules copy command in App.vue

[rakshitx1]

Description

During the ESP-IDF extension setup in VSCode on a Linux system, the user is prompted to copy the 60-openocd.rules file at the end of the configuration process. However, the generated command contains an incorrect cp option (--update=none), which results in an error.

This PR corrects the command by replacing --update=none with the valid -u option, ensuring the file copies correctly to /etc/udev/rules.d/.

Steps to test this pull request

1. Configure the ESP-IDF extension in VSCode on a Linux system.

3. Copy and execute the command in a terminal.

Expected behavior:

No error messages should appear, and the file should be correctly placed in the target directory.
