Escape title in footer link

[Baltazardoung]

0dd4831 introduced a regression within the code check via html-Proofer for a document with double quotes in the title.

Attribute set `<a href="quality_profiles_XXX_php.html" class="md-footer__link md-footer__link--next" aria-label="Suivant: Les " quality="" profiles"="" XXX"="" rel="next">
          <div class="md-footer__title">
            <div class="md-ellipsis">
              <span class="md-footer__direction">
                Suivant
              </span>
              Les "Quality Profiles" XXX
            </div>
          </div>
          <div class="md-footer__button md-icon">

Thanks for reporting. Possibly fixed by applying the ... | e Jinja filter for escaping.

[Baltazardoung]

Thank you for this confirmation. In our processes and CI, we automatically use the latest version of the docker mkdocs-material image.

So we are looking forward to the fix in your repository 😄.

Workaround until I find the time to provide a fix: pin version to 7.1.6.
