Celeste.exe is difficult to access on Mac

[Zygahedron]

Starting Lönn from Olympus the first time, it told me to select Celeste.exe, which isn't a normal thing on mac, so I assumed giving it Celeste.app (technically a directory) would work, but instead it crashed with this error:

Error

My next idea was to give it the Celeste executable from within the .app, but you can't access that directly within the file picker dialogue, so I had to open a separate window to drag on it... but that just reopened the dialogue, so evidently that was wrong too.
It turns out there is a Celeste.exe elsewhere in the .app, so I guess the instruction isn't wrong, but it could certainly be made more clear.
Ideally, it should be able to find Celeste.app/Contents/Resources/Celeste.exe automatically, and update the initial text to reflect that.

It already does this, your issue is a regression at some point and has already been fixed.
