Why this repository uses different gradle dependency implementation?

[Nephys222]

I wonder why libretube uses such as:
implementation libs.androidx.navigation.fragment implementation libs.androidx.navigation.ui...
instead of
implementation 'androidx.appcompat:appcompat:1.3.1' implementation 'androidx.cardview:cardview:1.0.0' implementation 'androidx.constraintlayout:constraintlayout:2.1.3' ?

For better structure, libraries are located in gradle/libs.versions.toml
