chore: update deps

[rokk4]

The deps are getting a little bit out of date, so I updated them. Test and example App work fine. This includes WebRTC 0.9.0. For example I am seeing some problems like this: Because every version of livekit_client from git depends on device_info_plus ^3.2.3 which depends on device_info_plus_windows ^2.1.1, every version of livekit_client from git requires device_info_plus_windows ^2.1.1. And because device_info_plus_windows >=1.0.0-nullsafety.0 <3.0.0 depends on ffi ^1.0.0, every version of livekit_client from git requires ffi ^1.0.0. And because file_picker >=5.0.0 depends on win32 ^2.7.0 which depends on ffi ^2.0.0, livekit_client from git is incompatible with file_picker >=5.0.0. l

@rokk4 Thank you for your PR, but before that we decided to downgrade some dep settings to ensure that we can cover flutter 2.8.x+, which supports flutter versions within half a year
