docs: update readthedocs on release events

[ReenigneArcher]

Description

We need to change the "default_branch" property in readthedocs in order to make the "latest" version point to our latest stable release.

This workflow will probably become a global workflow and replicated from .github. See: LizardByte/.github#341
