Read and Docs: How to fix "Config validation error in build.os. Value build not found."
Recently, I encountered a build error whiling using the Read the Docs service. The error message displayed was as follows.
Error Config validation error in build.os. Value build not found.

After some investigation, I discovered that the root of the problem lay in the configuration of the .readthedocs.yaml file. To resolve this, I made specific changes to the file.
The detailed modification can be viewed in the commit linked below.
