[jcomm] Events page unreadable in dark mode

[Hackwar]

When visiting https://community.joomla.org/events.html with my Firefox and my OS being set to dark mode, the website is basically unreadable.

There’s not much we can do about this, this is where people copy into tiny from a google doc and don’t strip any formatting. You can see for all the other events the text is legible other than the JUGL event
