[Feature] | Update download instructions to follow gradle.kts code style

[hrodrick]

Which kind of problem this feature would address? Please describe.
Currently the instructions to download the library as a dependency uses a .gradle file structure. Which is now obsolete, the preferred way to use gradle for android development is with gradle.kts files, so we need to update the section.

Describe the solution you'd like
Currently we have the following the line for adding jitpack repository: maven { url 'https://jitpack.io' }
It needs to be updated to : maven { setUrl("https://jitpack.io") }

Please also review what else needs to be updated in order to download the library correctly.
