fix(ci): Fix metro blocklist blocking expo-symbols android dir and update comments

The blocklist regex `.*\\android\\.*` was too broad - after being combined
by Metro's exclusionList, it blocked `expo-symbols/build/android` directory
from being resolved, causing Android bundle export to fail.

Scope the regex to only block the sample app's own android/ build directory.

Also update comments to reflect SDK 55 and RN 0.83.
