PR Summary

• Adjustment of Condition in esptool
  The condition set to execute a certain block of code in the esptool component was modified. This means that instead of looking for if a specific setting (WSL_ROOT) is defined or not, the code will now check if the new setting (WSL_COMPORT_POWERSHELL) is equal to 1. This change will allow better control over when certain sections of the code are executed, enhancing the functionality and efficiency of the tool.
