[BUG] Error: EISDIR: illegal operation on a directory, realpath 'R:\Temp'

[MrDemocracy]

Describe the bug
When using a ram disk for the Temp path Flashpoint crashes whenever I try to change the config.
The usage of realpath on this line could be responsible for the bug:

launcher/src/back/util/misc.ts

Line 382 in 9e768b2

return path.join(await fs.promises.realpath(os.tmpdir()), uuid() + '.' + ext);

To Reproduce
Steps to reproduce the behavior:

1. Create a ram disk (could be done with ImDisk Toolkit)
2. Set your Temp path to the new ram disk volume you just created by changing the environment variables (can also be done directly from ImDisk)
3. Open flashpoint and change something in the config tab
4. See error

Expected behavior
It should be possible to have the temp path set to a non-default path without Flashpoint crashing.

Desktop (please complete the following information):

• OS: [Windows 10]
• Flashpoint Version [Infinity 13.0.2]
• Log text (if relevant)
