Voiceovers Allowed for Untranslated Fields

[U8NWXD]

Describe the bug
Creators should not be able to upload voiceovers in language X for fields that have not yet been translated into language X. The modal says so, but allows uploads.

To Reproduce
Steps to reproduce the behavior:

1. Create an exploration with some text field(s)
2. Switch to the translation tab
3. Make sure you are in voiceover moe
4. Upload a voiceover for a language you did not write the exploration in and that does not have translations

Observed behavior
The upload is accepted, and the tab and card turn green to indicate voiceovers have been added, even though the modal says that translations are needed first.

Expected behavior
The upload should be rejected.

@U8NWXD, Currently the exploration is being completely managed by exploration editor, translators and voice artist. We haven't added any such validation of "Allowing voiceover only if translation exist." for conditions like translator/editor deleted original text/translation although the voiceover still exists.

In the future, the translation will be handled by the community and there will be less chance of this kinda issue to happen. I'm moving this to the "Translation and voiceover team", we will go through this issue.

@DubeySandeep the critical user paths document reads:

Try adding voiceovers for a different language.	You should not be able to do so, without adding written translations for that language. The modal should tell you so.

I've left a suggested change to remove this row from the document since this validation is not yet performed

Sounds good (regarding removing it from the testing doc). Note: Once this issue is fixed, please make sure you notify either Chris/me and we will add this back to the testing journey.
