I18n: Translate "Storyboarding" file template

File template names are only extracted in the
`blo_is_builtin_template()` versioning function, not the template
files themselves.

This commit adds the recent "Storyboarding" template to the list of
built-in templates, which allows extracting it for translation.

Reported by Ye Gui in #43295.
