Merge #559 by AzazelSensei: docs: refresh getting started for rules_android 0.7.3 #351

The getting started snippet still pinned WORKSPACE to 0.6.0-alpha1 (yanked on BCR) and bzlmod to 0.6.5. I updated both to 0.7.3, put bzlmod first, and pointed at examples/basicapp.

Fixes #351

Closes #559

-## Getting Started
-To use the Starlark Bazel Android rules, add the following to your WORKSPACE file:
+A complete sample app lives in [`examples/basicapp`](examples/basicapp). Set
+`ANDROID_HOME` to an Android SDK and run `bazel build //java/com/basicapp:basic_app`
+from that directory.
 
+## Getting Started
+
+Bzlmod is the recommended way to depend on these rules. Add the following to your
+`MODULE.bazel` file. `0.7.3` is the latest release on the Bazel Central
+Registry; pin a newer version if one is available.
+
+```starlark
+bazel_dep(name = "rules_java", version = "9.0.3")
+bazel_dep(name = "bazel_skylib", version = "1.8.1")
+
+bazel_dep(name = "rules_android", version = "0.7.3")
+
+remote_android_extensions = use_extension(
+    "@rules_android//bzlmod_extensions:android_extensions.bzl",
+    "remote_android_tools_extensions")
+use_repo(remote_android_extensions, "android_tools")
+
+android_sdk_repository_extension = use_extension("@rules_android//rules/android_sdk_repository:rule.bzl", "android_sdk_repository_extension")
+use_repo(android_sdk_repository_extension, "androidsdk")
+
+register_toolchains("@androidsdk//:sdk-toolchain", "@androidsdk//:all")
+```
+
+The Android SDK is resolved from `ANDROID_HOME`.
+
+WORKSPACE remains supported. Add the following to your WORKSPACE file:
 
 ```starlark
 load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
 http_archive(
     name = "rules_android",
-    sha256 = "fe3d8c4955857b44019d83d05a0b15c2a0330a6a0aab990575bb397e9570ff1b",
