Depencency jenssegers/agent conflicts with Jetstream

[andrewdrake]

The jenssegers/agent package hasn't been updated in 4 years and has a dependency conflict now with Laravel Jetstream.

- laravel/jetstream[v4.1.0, ..., v4.2.2] require mobiledetect/mobiledetectlib ^4.8 -> satisfiable by mobiledetect/mobiledetectlib[4.8.01, ..., 4.8.05].
- You can only install one version of a package, so only one of these can be installed: mobiledetect/mobiledetectlib[2.7.6, ..., 2.8.45, 4.8.01, ..., 4.8.05].
- Conclusion: install mobiledetect/mobiledetectlib 2.8.45 (conflict analysis result)
- Root composer.json requires laravel/jetstream ^4.1 -> satisfiable by laravel/jetstream[v4.1.0, ..., v4.2.2].

The issue is that jenssegers/agent requires the deprecated version 2.7 version of mobiledetect/mobiledetectlib

jenssegers/agent#207

Maybe this fork works for this project: https://github.com/asika32764/agent
