KEP 3836 - promote to beta

[alexanderConstantinescu]

What type of PR is this?

/kind feature

What this PR does / why we need it:

kubernetes/enhancements#3836 was promoted to beta in 1.29, see kubernetes/enhancements#4258. I however forgot to update the feature gate in 1.29....I only realised this now when going over the KEP work for 1.30 :/

I am therefore updating the feature gate to beta here, following what was already agreed.
