[housekeeping] Bump dependencies

[bbjubjub2494]

• Kotlin 1.5 breaks jacoco reports, hence it has been skipped
• Android SDK 4.2 and/or gradle 6.7 break some stuff, hence they are not there

I would also suggest bumping the gradle version to 4.2.1 (line 11 in build.gradle)

very good suggestion. (unless you're like me and you haven't updated Studio, but that's on me)
