cal.com [CAL-3991] clean up our i18n translation files

the bounty here is to clean up every common.json file for all languages and remove unused strings

unused strings happen when the code is being removed, but not the language file

example:

{t("hello_world")} is being removed

but

hello_world: "Hello World" still shows up in all common.json files

This leads to a ton of extra translations and people asking for context because they dont see the string in the product anymore.

The task at hand:

write a script that can be run once for the PR
and submit the script so we can run it every now and then. does not need to run for each PR. once a month manually is fine

⚠️ Caution:

sometimes the strings are _one and _other:

so you might run a "Search and Replace" operation that could kill active strings, cause the _other would not show up in code:
