[Inkscape-translator] Website: small update for Debian download links

Dear website translators,

Martin has updated the download links for Debian to point users to a way how they can get the current Inkscape version.

This concerns the Download and the Linux pages: https://inkscape.org/en/download/ https://inkscape.org/en/download/linux/

For concrete changes see attached screenshot.

Thanks! (and a happy spring time to everyone on the northern hemisphere - *almost* (but only just) too beautiful for translating websites ;) )

Kind regards, Maren
