feat: Add a fluid container to allow for limiting the maximum width of the content [backport from master]

[Lunyachek]

This is backport from master #276

Our proposal is to add <div class="container-fluid"> inside the <main id="main-content"> block. This will allow limiting the maximum width of the content when necessary. Otherwise, the content will span the entire width of the page, as it would without this div.

Example screenshot width content max-width
