feature: youtube embedded video

[S4ND1X]

We need a video player for youtube videos inside the details screen

For this we need to add/modify the following items:

• Add the possibility to add a link to a Youtube video in the create habiut
• Add the new attribute on HabitDTO
• Validate that is a youtube link, for this wee could use Regex expression
• Cannot create habit if the youtube link is not a a valid one (but it can be empty)
• Use that link in the details screen and use it on the video player

@marleneharms I think that you should do this since you did the details screen and know how to pass the arguments 💜
