feat(cli): add bundle.android config to build and sign the apk file in release mode (#4062)

* feat(cli): add `bundle.android` config to build and sign the apk file in release mode

Add this to `Dioxus.toml`

```toml
[bundle.android]
jks_file = "path/to/jks file relative to Dioxus.toml"
jks_password = "jks_password "
key_alias = "key_alias"
key_password = "key_password "
```

When release flag is enabled and this configuration exists  at the same time, use `gradlew assembleRelease` build and sign apk file

* fix merge conflict

* only run assembleRelease when bundle exists
