Created polish language translation

Fixed translation errors in Vietnamese locale file `locales/vi-VN/translation.json`

- Restore Gravatar functionality
- Add new button for "Use Initials"
- Set both buttons to use text-left class
- Update toast property autoClose to duration (wrong library, my bad!)
- Update toast messages to clarify that this isn't "Gravatar" but "avatar"
- Add i18n text to en-US/translation.json

Created Turkish translation file

* Tooltips added to show full model name and warning regarding vector storage
* Send toast error and return early if more than a single front slash is detected
* Extend toast duration for model update action
* Add i18n en_US translation
* Remove commented code copied from existing function

Updated all translations to have a Dutch translation.

This reverts commit 9763d885.

Translation values for en-US are not necessary, the keys will be
used as fallback.
