Remove all mentions of Travis from the codebase

Travis CI is no longer functioning and with sympy#24232, we now no longer require it for pushing the development docs, which was the last remaining thing it did that was not on GitHub Actions. The ON_TRAVIS variable in the tests has been renamed to ON_CI, and is based on the CI environment variable being set (see https://docs.github.com/en/actions/learn-github-actions/environment-variables).
