[suggestion] add missing text strings (to translate)

[SofyUchiha]

Hi! I noticed that it is not possible to translate certain small texts related to:

• the number of subscribers of a channel (subscribers)
• who uploaded the video (uploaded by...)
• age of the video (.... hours, mouths, years ago)
• age of a comment (.... hours, mouths, years ago) I emphasize this because the string "like" has been translated. Maybe these strings can be added. Anyway, I attach a screenshot in Spanish with the texts "to translate" underlined in red (to better explain myself) Thanks for all your work!

This strings are obtained directly from YouTube. Maybe needs some language change API if it exists.

It appears that locale of strings obtained from YouTube depends on the settings of Invidious instance. Since this is impossible to change on the client side this issue is unlikely to be fixed.
