MinSdk in security crypto 1.1.0-alpha04 was updated to 21

[AdamGrzybkowski]

In the build.gradle there's a comment

Min SDK should be aligned with min SDK in androidx.security:security-crypto

The minSdk of the androidx.security:security-crypto in version 1.1.0-alpha04 was updated to 21 instead of 23.

Are you considering downgrading the library minSdk?

I'm going to drop security-crypto from dependencies someday. However, I should check If I use particular StreamingAead APIs available in Tink only from SDK 24.
