[cleanup] Remove removed functions from `Doc/data/refcounts.dat`

[picnixz]

Feature or enhancement

Proposal:

This is a follow-up of #122331 (comment) where a typo was not spotted. Some functions are still in this file but were removed in previous versions (see the corresponding PR for how I detected them).

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
