This directory helps with review of generated files where we lagely want the content to be custom.
The project README.md is a good example. We heavily custimize
README.md based on our particular use case. There are also important
changes to the generated README.md that should be reviewed when it is
updated. These include things like new minimum language versions, or
client API changes.
If you add the README.md to the .openapi-generator-ignore list then
you never see the updates, making it easy to miss things. If you don't
add it to the .openapi-generator-ignore list then any uncommitted
updates to the README.md are lost when running
script/generate_language.
