[Fix] Remove get folder parent util fxn, prevent text input in install modal path field

[BrettCleary]

Summary

This closes #672

waiting for upstream PR merge here Alex-D/check-disk-space#29

Background

https://github.com/Alex-D/check-disk-space is used by both Heroic and HyperPlay to check available disk space. The getFirstExistingParentPath function was copied from this package into the utils file on this PR Heroic-Games-Launcher/HeroicGamesLauncher#1575. This function is now duplicated in 3 places, in the original package, in heroic utils, and in hyperplay utils.

There is a bug when checking disk space for Z: where Z is a non-existent drive on windows #672. The function gets caught in an infinite while loop and crashes HyperPlay. Because the InstallModal install path text field was editable, a user could type this out in the text field and (since disk space is calculated after every keystroke) this would crash HyperPlay.

This PR

• Consolidates the function getFirstExistingParentPath back into the @hyperplay/check-disk-usage package until an upstream PR is accepted
• Prevents text input in the install modal, forcing the user to use their respective file explorer which has better error handling
• Fixes the previous infinite while loop bug and adds more testing to check-disk-usage
