build(deps): bump sqlite from 2.1.0 to 2.2.0

[mikehardy]

We want the new version of the sqlite dependency but

...it requires compileSdkVersion 31
...which requires JDK11
...which requires newer Android SDK commandline tools (used to install NDK)

So,

• switch our NDK github actions install method to setup-ndk - should work
• switch our JDK to 11 in github actions and enforce it
• then switch sqlite versions and Android API

Variables are at least extracted so may be modified in one spot See #154 and #153 - possible easily because of #176

[mikehardy]

Did not realize we were still on JDK8 here, while API31 requires JDK11, added a commit before the API31 bump to move to JDK11

[mikehardy]

I forgot Android SDK bundled command line tools don't work with JDK11 🤦 what a yak shave
Added different NDK install method so we don't need sdkmanager

Built on #178 now, will rebase+push after it succeeds (assuming it succeeds) but this gets a run through CI in the meantime
