ci(android): pass setup-android packages as one space-separated string

The YAML '|' multiline made sdkmanager see a single package called
'platforms;android-34\nplatforms;android-30\nbuild-tools;34.0.0\n
platform-tools' (literal newlines and all) and exit 1 with 'Failed
to find package'. The action's docs use a single space-separated
string.
