Change the log level of RPC connection established

[rqx110]

pyinstaller/PyInstaller/fake-modules/pyi_splash.py

Line 99 in 061761c

_log(20, "IPC connection to the splash screen was successfully established.") # log-level: info

When I use Splash feature, it always display, which is not what I want.
Can we change this message level to Debug?

Yeah, both

pyinstaller/PyInstaller/fake-modules/pyi_splash.py

Line 99 in 061761c

_log(20, "IPC connection to the splash screen was successfully established.") # log-level: info

and

pyinstaller/PyInstaller/fake-modules/pyi_splash.py

Line 141 in 061761c

_log(20, "Connection to splash screen has already been closed.") # log-level: info

should be downgraded from INFO to DEBUG.
