PDF Editor page contains obsolete references and screenshots

[flodolo]

I just pointed a user to https://www.mozilla.org/en-US/firefox/features/pdf-editor/

Turns out the page is quite out of date (e.g. at least the icon for Add text has changed).

There is also the signature feature now, which is not showed.

We should either update the page, or remove it and redirect to https://support.mozilla.org/kb/view-pdf-files-firefox-or-choose-another-viewer.

Is this equivalent page https://www.firefox.com/en-US/features/pdf-editor/ correct enough now for us to close this ticket?

@stevejalim it is still the same as when the ticket was filed.
