[cronet_http] Upgrade to kotlin 1.8.10 (#1789)

* [cronet_http] Upgrade to kotlin 1.8.10

Fixes this warning:

```
Warning: Flutter support for your project's Kotlin version (1.8.0) will soon be dropped. Please upgrade your Kotlin version to a version of at least 1.8.10 soon.
Alternatively, use the flag "--android-skip-build-dependency-validation" to bypass this check.

Potential fix: Your project's KGP version is typically defined in the plugins block of the `settings.gradle` file (/Users/bquinlan/dart/http/pkgs/cronet_http/example/android/settings.gradle), by a plugin with the id of org.jetbrains.kotlin.android.
If you don't see a plugins block, your project was likely created with an older template version, in which case it is most likely defined in the top-level build.gradle file (/Users/bquinlan/dart/http/pkgs/cronet_http/example/android/build.gradle) by the ext.kotlin_version property.
```
