[REG 4.4.1->4.5.0][Windows 10]: When using gdb it will add a Path env var with the modifications needed, whereas GDB will expect a PATH env var

When using gdb it will add a Path environment variable with the modifications needed, whereas GDB will expect a PATH environment variable. Windows 10 uses Path instead of PATH now and since we are respecting the case of the environment variable, when the change is made to include Qt it ends up creating a new one since GDB sees it as PATH and not Path.

Therefore, it needs to be modified to update PATH regardless of the case of the original for gdb
