[0.17.1] Intro scenario completion asks for screenshots from wrong directory

[malventano]

Asks for screenshots from 'script_output' directory but the real name on disk was 'script-output'.
Also, screenshots generated on 4k or ultrawide displays may be too large to email easily, FYI.

Besides that, maybe it's an idea to point out that the script-output directory is not inside the steam directory.

I had to do a full disk search to find out that the screenshot was inside the folder: C:\Users\{UserName}\AppData\Roaming\Factorio\script-output\campaign_base_screenshots\
