Update notify to v0.9.3 to fix deprecation warning on MacOS 13.

[adlerjohn]

Overview

Running make build on MacOS 13 (Ventura) gives

$ make build
--> Building Celestia
# github.com/rjeczalik/notify
cgo-gcc-prolog:217:2: warning: 'FSEventStreamScheduleWithRunLoop' is deprecated: first deprecated in macOS 13.0 - Use FSEventStreamSetDispatchQueue instead. [-Wdeprecated-declarations]
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreServices.framework/Frameworks/FSEvents.framework/Headers/FSEvents.h:1138:1: note: 'FSEventStreamScheduleWithRunLoop' has been explicitly marked deprecated here

Fix this by updating rjeczalik/notify to v0.9.3 as recommended here: ethereum/go-ethereum#26168 (comment). Updating go-ethereum might be an alternative but would be much more cumbersome.

@adlerjohn, is this RFR?

[adlerjohn]

no longer needed as of #2253 which did the much more cumbersome job of bumping go-ethereum
