Update list of profiles and add a page on profile addons

[WeirdRubberDuck]

• Removes the profiles that no longer exist (Default Full, Asteroids, Touch)
• Add the newly added profiles (BeppiColombo and Euclid)
• Restucture so that all mission profiles are listed under "Mission Profiles" (similar to "Space Weather Profiles")
• Adds a brief page about Profile Addons, and moves the Asteroids information there
• Remove a building content page about asteroids and move this info to the addons page, to limit duplicated content. Also cleaned up this page
• Replaces the JWST "Nothing to see here" with a note similar to the night sky profile

closes OpenSpace/OpenSpace#4039

Note that I have not updated or verified the content of any of the asset pages. This includes the list of asteroid groups, even though I've done a bit of cleaning/restructuring of the information on this page. For the new profiles, I added just a minimal sentence describing the profile

Here's how the navigation bar looks after this change:

	This profile shows the trajectory of ESA's Euclid mission to the Sun-Earth L2 point, where it will observe billions of galaxies to better understand dark energy and dark matter.
