[mediawiki/core@master] Italicise redirects on Special:MostTranscludedPages

https://gerrit.wikimedia.org/r/792297

Here is the CSS I'm adding in the patch:

.mw-special-Mostlinkedtemplates .mw-redirect {
    font-style: italic;
}

A few notes:

• I'm precisely targetting Special:Mostlinkedtemplates (for now), but maybe we want to italicise redirects on other pages as well.
• Notice this CSS is loaded on all special pages (see rMW15eac4c27939).

Uploaded a new patch:

.mw-special-Mostlinkedtemplates .mw-spcontent .mw-redirect {
    font-style: italic;
}

The selector is more specific, so that we target exclusively the templates listing, avoiding the MediaWiki interface around.
Alternatively, the slightly broader #mw-content-text or .mw-body-content could have been used.

I don't think we should really be using italics to show redirects.

There's a pressing need to use italics in some titles, e.g. https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style/Titles_of_works which is the subject of other feature requests, in particular T350648.

So, it would be better and clearer to use, as [[Special:WhatLinksHere]] does, the suffix (redirect page) ‎after the name of the page.
