emojis not displayed correctly in README

[ilka-schulz]

When reading the README on github.com then some emojis are not displayed correctly but some text is displayed instead. I assume Github has changed their emoji definitions...

affected emojis:

• :bride_with_veil:
• :beetle:

The 👰‍♀️ is a GitHub bug.

The 🪲 appears to be a GitHub bug as well but there is :lady_beetle: 🐞 .
