Code Review

This pull request performs a broad standardization of Groovy Gradle build files across numerous packages. The changes apply more modern Gradle DSL syntax, such as using double quotes, parentheses for method calls, the = for assignments, and updating properties like minSdkVersion to minSdk and lintOptions to lint, in preparation for a migration to Kotlin Gradle files.

The standardization appears to be incomplete for packages/local_auth/local_auth_android/android/build.gradle. This file still contains older syntax (e.g., single quotes for group and version, and method calls without parentheses) that has been updated in other files in this PR. Applying the standardization consistently to all files would better achieve the PR's stated goal.
