Exclude permalink from word selection

[pyhedgehog]

Here are screenshot of problem:

When I double-click on section header to copy it to my code I don't want to finish with permalink-emoji within my YAML. :-)
Seems it rathes simple to fix - permalink matches .rst-content dl dt .headerlink, selector in theme.css. So all we need is to add user-select: none; like (and possibly a lot of browser-specific lines) there. At least this works-for-me in Firefox.

@felixfontein it's been 7 months since your PR on the sphinx theme and no movement. Do you think we could patch this in the ansible sphinx theme instead? https://github.com/ansible-community/sphinx_ansible_theme
