Summary
Japanese localization of Announcement's email notification contains some issues. Specific to this request, the widget name is not translated

Steps to Reproduce

1. Set announcements.entry.check.interval=1 in portal-ext.properties, as this will speed up the announcements entry check from 15 minutes (default) to 1 minute
2. Configure a working SMTP server or tester to Liferay
3. Add a user with a valid email address and set Japanese (日本語) as their display language
4. Go to the user's Account Settings > Preferences > Alerts and Announcements Delivery > Check Email for "General", then Save
5. Go to Control Panel > Configuration > Announcements and Alert
6. Add Announcement with default configuration
7. Wait for email notification to be sent to the new Japanese user
8. Examine the email's subject

Actual Results
Widget name in subject of the email is "Announcement" in English.

Expected Behavior
Widget name in subject of the email is "お知らせ" as in the localized component name.

Note: This does not affect Alerts widget which has properly localized email notifications which indicates it is coming from 警告.
