Use objects instead of arrays in day-names and month-names

[superbiche]

I'm using Vue-i18n and Weblate for our translation workflow.

Unfortunately, Weblate, but many other tools like dot-object or even deepmerge can have a hard time handling arrays.

We can get to the following common sense:

• day-names can be an object like { 0: 'Domingo', 1: 'Lunes' } or { sunday: 'Domingo', monday: 'Lunes' }
• month-names can be an object like { 0: 'January', 1: 'February } or { january: 'Enero', february: 'Febrero'}

I honestly don't know which is best. I find the string-based one easier to read right now, but I'm pretty sure that once we change the code accordingly, integers will be much easier to work with, and allow easier props customization.

I've added this to v4 but maybe v5 huh, this may be too much work and delay v4 without a good enough reason

@superbiche What about this?

So you may use Object.values or Object.entries javascript functions
