Title of Welcome Slide is not localized

[hissy]

"Take a few minutes to learn the basics" is always English:

bedrock/assets/cms/components/Announcement/Slide/WelcomeSlide.vue

Line 3 in 3bbbc74

<announcement-header title="Take a few minutes to learn the basics"></announcement-header>

"Tell us a little about your site" is the same:

bedrock/assets/cms/components/Announcement/Slide/CollectSiteInformationSlide.vue

Line 4 in 3bbbc74

<announcement-header title="Tell us a little about your site"></announcement-header>

I think more components have still not been translated yet.
