docs: add "PlantUML package and PlantUML on the GNU/Linux distribution" page [skip ci]

[The-Lum]

Hi,

To answer to:

• 1572

Here is the links of plantuml version on:

• the [most popular] software package management systems;
• the [most popular] GNU/Linux distributions.

This is an attempt, and we can change the form in the future (why not table instead list..., to debate...).

Regards, Th.
