Use a new deps for HTML5 parser

`electrolinux/php-html5lib` was quite old and incompatible with the upcoming Composer 2.0.
Jumping to `masterminds/html5` for the same result. Also the lib is maintained.

Also:
- keep README in vendors
- use new Scrutinizer engine
- test with lower deps
- remove php-coveralls dev deps and download the phar during the CI build
