This function imports the Ubuntu font from the 'fmggp2' package assets, adds it to the available system fonts, and sets it up for use with graphing tools by enabling automatic font loading via 'showtext'.
Fonts Import
The fonts are imported using the font_import function from the extrafont
package, which allows for the use of fonts in PDF and PostScript graphics.
The function does not prompt the user during the font import process.
Fonts Addition
Once imported, the Ubuntu font is added to the available system fonts with
the font_add function from the sysfonts package.
Enabling Font in Graphics
Finally, the showtext_auto function from the showtext package is used
to automatically use the font in graphs, facilitating the immediate
application of the font in graphical devices.
