Dumb SEO attempt

[Miepee]

This PR tries to do some (dumb) search engine optimization for the cases where people search for "{game} randomizer".
From looking at the results for a few games, the one websites that scored highest, always included "{game}" and "randomizer". The closer the terms were together, the higher they scored as they were more accurate to the query.
I.e

• Bash's github page, which is literally filled with Metroid Prime Randomizer
• various pypi and github projects such as Cave Story Randomizer v2.0, randomizer patcher for Metroid Dread etc.
• our project's github readme: a randomizer [...] Metroid Dread. Metroid Prime 2: Echoes. [sic, dont ask me why prime1 isnt there]

This lead me to notice:

1. We dont have any page where list both "randomizer" and all our supported games. However, I feel like putting that on the main page is distracting. We could put it on the about page, but I dont think pushing our about page is a good idea? Might be worth a shot tho in a later PR, since more clicks to our page => more chance of people downloading.
2. The pages that have "randomizer" and the games name in their main page, such as AM2R (AM2R already has a built-in randomizer) or MSR (but in the randomizer, this has been changed), do score relatively high

The solution? Include Randomizer on each game page, but in a way where it doesn't disrupt the flow of text. MDN mentions that headers get ranked higher for SEO.
So I just added it invisibly next to the game name.

Potential caveats:

• Search engines might be smart enough to block invisibly styled elements.
• Search engines will likely display the randomizer text, akin to this (inspector'd):
  
• Certain things that ignore CSS properties (screen readers maybe? Esoteric text browsers?) will also display the randomizer text

oops! this is specifically against policy and will have us penalized in search results
