fix: include missing icons to Lumo icon sets

[web-padawan]

Description

Some SVG icons were missing from the iconset files from because of incorrect regex.
Updated to include align-center, align-left and align-right icons.

Also changed the namespace for vaadin-iconset to use lumo (see #1988)

Depends on #1988 and will be rebase once that PR is merged.
