Provided more information about bundled plugins

As discussed on mattermost. We need to better communicated that the github packages include certain plugins and what they are.

Some ideas:

• adjust download file names to something like "Cutter-v2.4.1-Windows-x86_64+plugins"
• list in the README page
• cutter.re website 2 places

For the website we could also do something like this (although it is pretty long. Not sure if it is worth it to use so much space for the list):

Having a plugin list at the top seems a bit much. Maybe a square button with icon not even full word, and "plugins" text as tooltip, which scrolls the page to the list next to "download" section.

It looks for sure better. Though I don't know if people would click on it. Maybe using some i icon (for details/information)?

i actually prefer a fine print saying "includes: xxx, yyy,zzz plugins."
