Drop support for YouTube handle (P11245)

[RVA2869]

Description

Why:

To avoid duplicate social media accounts.

Example:

Asikkala
Wikidata: Asikkala

This seems related to #302.

Perhaps we should COALESCE to take the YouTube name if it exists, and otherwise the Channel ID, but never both?

Personally, I'm not a fan of the YouTube handle property on Wikidata.
Because they are 90%+ auto regenerated and they can be modified by the owner.
But that's a personal preference.

Perhaps we should COALESCE to take the YouTube name if it exists, and otherwise the Channel ID, but never both?

Or alternatively add support for subject named as (P1810) as a qualifier. BorkedBot already adds them and if the website sync was performed before BorkedBot entered the property, no value should change.

I don't understand this argument. Surely, the Channel IDs are 100% generated, so that shouldn't in itself be a problem, or what am I missing?

This is about the YouTube handle.

If this is related to #302 (which is related to #67), then we should try to avoid using automatically generated/numeric identifiers,
to increase readability (for humans).

I too think we should drop support for it, having some type of generic support for "subject named as" would be much better.
