This change updates the Android Target API to 36 to satisfy the upcoming
annual Play Store Aug 31 requirement. It updates Keyman for Android to
use API level 36 by changing the compileSdk and targetSdkVersion
properties to 36.
Also update `compileSdkVersion` and some reformatting in `README.md`.

This change fixes two problems that cause a script error in Sample1 app:
- add internet access permissions so that the Sentry server can be reached
- explicitly set the default keyboard since sil_euro_latin keyboard is not
included in the sample apps. This works around #16215.
Fixes: #16180
Build-bot: release:android
We use SIL EuroLatin as fallback keyboard. If that is not installed,
previously we output an error which showed up as a toast for the user.
This change now outputs a warning instead of the error for the default
keyboard.
Also changed the KeyboardHarness test app to set a different keyoard as
default.
For keyboards that are v19 or later, always reserve space for the KMX+
header that will be written out in kmc-kmn, to avoid rewriting the whole
file. At this time, zero out that space.

Resolves Gradle deprecation and language version warnings
```gradle
Java compiler version 21 has deprecated support for compiling with source/target version 8.
```
The `java.toolchain.languageVersion` syntax is a superset that covers the previous syntax `android.compileOptions`
Previously the builder scripts defined a readonly `VERSION` environment
variable for the Keyman version. That caused problems when another
(external) script tried to define a `VERSION` variable. We encountered
this problem when trying to move the TC build steps of a configuration
into a single script (#13399) when we tried to source `~/.nvm/nvm.sh`.
This change uses a Keyman specific prefix for the version variables and
renames `VERSION` → `KEYMAN_VERSION` etc. Unfortunately these variables
are used in a lot of places, so this turned out to be a bit of a yak
shave.
