fix(android): move bundle task lookup to afterEvaluate, restore warning

Follow the SAGP pattern (sentry-android-gradle-plugin/util/tasks.kt):
register project.afterEvaluate{} inside onVariants{} so that task lookup
is deferred until after all plugins have registered their tasks.

onVariants fires during project evaluation — before the task container is
complete — so tasks.configureEach registered there could miss late-registered
bundle tasks. afterEvaluate runs after all onVariants callbacks (including the
React Native plugin's) have completed, making tasks.names reliable.

Replaces tasks.configureEach + gradle.taskGraph.whenReady with:
  - project.afterEvaluate for timing
  - tasks.names.contains() guard with inline warn() for missing tasks
  - tasks.named() for a targeted lazy reference (no container iteration)
