Feat: add weekly view to v2

[luisrondow]

Summary:

This pull request introduces the "Weekly View" functionality. The new feature enhances the library's capabilities by providing users with a dedicated weekly calendar view

Changes:

• Added the "Weekly View" functionality to v-calendar
• Implemented necessary components, styles, and logic to support the weekly view feature
• Ensured backward compatibility with existing features in v2
• Does not break the previously existing functionalities

@nathanreyes any chance of you throwing this into a 2.4.3 release? We're in the middle of migrating an app but need to push a feature out in the meantime with a weekly view. Unfortunately (and much to my annoyance) we can't wait for the migration. I see this made it's way into v3 in the end?

Thanks!
