Build: do not upload `build.tool` to production S3 (#9098)
* Build: do not upload `build.tool` to production S3
Avoid uploading the .tar.gz to production S3 since we will be managing this via
CircleCI and an AWS orbs. See
https://github.com/readthedocs/readthedocs-docker-images/pull/179
We need to keep the upload part for development environment, tho.
* Build: join TOOL and VERSION with a `-` to simplify CircleCI routine
* Do not delete .tar.gz from local host when on production
* Remove old documentation
We are not going to run this command in production by hand anymore. However, in
case it's required, I'm linking to the issue that explains how to do it.
* Skip uploading when running from inside CIRCLECI
