Make Live BIOS version as symbolic link to directory

[emcek]

Move git version of BIOS form temp directory to regular one and link to Save Games folder to skip coping process.

Using windows cmd (not pwsh):

C:\Windows\System32>mklink /d "C:\Users\user1\Saved Games\Scripts\DCS-BIOS" "C:\Users\user1\Projects\dcspy\Scripts\DCS-BIOS"
symbolic link created for C:\Users\user1\Saved Games\Scripts\DCS-BIOS <<===>> C:\Users\user1\Projects\dcspy\Scripts\DCS-BIOS

There is a change we need Admin rights to do it:
