ro: translate setting block

[ghost]

Hello, friends!

Obsidian has become part of my day-to-day life and I am eager to contribute to the community by completing the Romanian language translation. Given the substantial size of the i18n files, I intend to submit a separate pull request for each block of translated strings as I progress.

In this pull request, I have included the following updates:

• provided new translations for all previously untranslated strings within the setting block
• revised existing translations within the same block to adhere to formal instead of informal speech
• ensured consistency in terminology throughout the translations, ~with plans to document these choices in a future pull request~ by providing a ro.termbase.md file, similar to practices adopted by translators in other languages

Kindly let me know if there are any additional steps I should take to align this pull request with the community standards.

Thank you for your time!

I've also added a ro.termbase.md file documenting my choices of words for this translation effort. I will update this file as I make further progress through the Romanian language translation.
