Update Usage Instructions to Include Permission Settings

Description

While utilizing the Introxt_Instagram.sh script from your GitHub repository, I encountered a permissions issue that required running the chmod +x Introxt_Instagram.sh command to grant execute permissions. However, this step is not mentioned in the current usage instructions.

I suggest updating the usage instructions in the README.md file to include a step for setting execute permissions using the chmod command. This addition will ensure that users are aware of the necessary permission settings before executing the script.

Proposed Changes

Provide instructions to run the chmod +x Introxt_Instagram.sh command to grant execute permissions to the script.
