Description

Fixes #38

This PR adds support for Fedora/RHEL-based distributions by detecting the package manager (apt, dnf, or yum) and using the appropriate package names.

Changes Made

• Added detectPackageManager() function to detect available package manager
• Added package name mappings for apt, dnf, and yum
• Updated installDependencies() to use the detected package manager

Testing Needed

⚠️ I don't have access to a Fedora system to test this.

Can someone with Fedora please test?

• @kaicsm (original reporter) - could you test this on Fedora 38?
• Would also appreciate testing on Ubuntu/Debian to ensure existing functionality still works

Package Name Mappings

apt (Ubuntu/Debian)	dnf/yum (Fedora/RHEL)
zlib1g-dev	zlib-devel
git-lfs	git-lfs
watchman	watchman
libfontconfig-dev	fontconfig-devel
adb	android-tools
