docs: Update setup instructions in README for current Android Studio

[edgarwideman]

• [x] I am not disclosing a vulnerability.
• [x] I am creating this PR in reference to an issue.

Issue Description

The Getting Started instruction in the README file were out of date for the current versions of Android Studio. For newer Android Studio projects created in Android Studio Bumblebee | 2021.1.1 or newer, the JitPack repository needs to be added into the root level file settings.gradle instead of build.gradle.

Closes: #1197

Approach

Edited the README.md file to reflect current steps required to setup a new Android Studio project.

TODOs before merging

• [x] Add tests (no need)
• [x] Add changes to documentation (guides, repository pages, in-code descriptions)
