Power Toys: v0.29.3 Release

This is patch release to fix two bugs 0.29.0 we deemed important for stability based on user feedback. 0.29.1 and 0.29.2 were internal tested but not publicly released.

• #8808 - FancyZone zones would occasionally not appear. This was caused by two uninitialized variables. During testing, there was a race condition so we missed it. Our push on adding in additional code analysis tools will hopefully catch these types of bugs.
• #8787 - PowerRename would throw regex errors when it shouldn't. We removed the error dialog for now and will add in a more targeted error catching block at a later time.
