docs: correct license references to MIT

The badge added alongside the SonarCloud badges claimed GPL v3, and the
README's License section claimed 'GPL 3.0 or later'. LICENSE has always
been MIT, so both statements misrepresented the project's terms on its
public front page. The section text predates this branch.
