README badges aren't consistently styled

[Jonathan-Zollinger]

Current Behavior

the first badge Java CI with Maven has what shields.io calls 'plastic' whereas the rest are shields' default style.

We want to be sure this isn't a one-off problem.

• [X] This problem is something that I can consistently produce.

Expected Behavior

all badges have the same style. the sheilds badges would just need to be changed to include ?style=plastic after the main query (before any link)

GOOD:

![GitHub issues by-label](https://img.shields.io/github/issues/PeanutButter-Unicorn/Tarvester/help%20wanted?style=plastic&link=https%3A%2F%2Fgithub.com%2FPeanutButter-Unicorn%2FTarvester%2Fissues)
