[TECHNICAL] Upgrade min SDK to Android 7.0 (v24)

[Aitorbp]

At the moment our min SDK version is Android 6 (v23) and I think that it could be time to upgrade to Android 7.0 (v24). This is needed to upgrade Kotlin version as well:

• Bump kotlin from 1.8.10 to 1.9.20 #4216

Users will be warned in 4.2 and it will be effective in the next feature release.

TASKS

• Research (if needed)
• Create branch technical/upgrade_min_sdk_to_android_7
• Development tasks
• Code review and apply changes requested
• Design test plan
• QA
• Merge branch feature/feature_name into master

official info shown by android studio that seems to be broken ftm. Will update as soon as is again available.

Official information shown by Android Studio continues broken, so we can take as a reference the percentages in Play Store referred to our app:

As you can see here, the percentage of users using Android 6 (SDK 23) is <1%. We could even upgrade it to SDK 25 (Android 7.1), which is still <1%.

7.0+ works for me 👍

Android Studio was updated to Android Studio Hedgehog version and now the window with this info seems to work:

Numbers are more or less similar to the appbrain webpage, so we could keep the same decision 👍
