chore(sample): fix lint and ts sample

[freeboub]

start fix eslint and tsc warnings in the sample

@KrzysztofMoch I backport your CI changes to be able to build the sample in this (Thank you again for that).
I want to enhance it be able to build with different build option (with or without ads typically).
What do you advise ? copy build-.yml to build--withads.yml or directly patch the file with something like:
run: cd examples/basic/android && ./gradlew assembleDebug --build-cache && ./gradlew clean && export ENABLE_ADS=true && ./gradlew assembleDebug --build-cache && cd ../../..

You can create separate "job" in build file so we will have build for Ads and build with non ads
