[Feature] Some widgets with fixed text as part of the UI are breaking the impression of localization

## Summary

A user on Discord was developing an app, with the UI in a non-English language. The text in buttons, text widgets, tab labels, dropdowns etc. can be bound from data so could be set to non-English copy. This creates the impression that developed app is a non-English app, and can be used with non-English speakers. But some widgets that have text in their UI break this illusion of localization. The date picker widget has the weekday labels in English, with no way to change or even use system default language. The table widget also has some internal UI elements whose text cannot be changed.

## Motivation

Most of Appsmith lends itself to be useful in developing applications that seem fully localized. But some parts of some widgets break this impression.

If there was a way to either set the language for these UI elements or just be able to set the text for these parts of the UI, the localization impression could be fully present in the application.
