new logo in public folder

[hell3nacht]

deleted the old logo files; added the new ones unure if it works to have a favicon.png instead of favicon.ico. added _white versions in case of needing them for e.g. a dark mode. (i have no idea how the whole commit / pull thingy works; in hope of kinda getting it right here the attempt of pushing it)

Great to see that you managed to wrestle your way through the labyrinth of git / GitHub. Thanks for the PR :). There are some some (easy to make) issues with this PR though:

• The favicon needs to be in the .ico format. Only then does the browser recognize it. There are online converters for this.
• You are trying to merge onto develop, the current working branch is rewrite though
• The logos (except the favicon) would, from my understanding, be more appropriately placed in the src/assets directory

I changed the PR to a Draft, this way it does not accidentally get merged. For more info check my private messages.
