SEND/SUB-operations are almost inivisible on sidebar due to missing background color

[FelixPopp]

Description The SEND/SUB-Operation in the sidebar ist not visible due to low contrast between font and background color

Expected result The background-color "bg-blue-600" should be applied

Actual result The background-color is not applied

Instead "false" is inserted as a CSS-class

Steps to reproduce

1. Open the demo https://asyncapi.github.io/asyncapi-react/
2. Enable the sidebar unter the configuration-tab

Troubleshooting

• Propably a follow up bug from #1040
• Seems like "bg-blue-600" is missing in the bgColors-Array here: https://github.com/AceTheCreator/asyncapi-react/blob/master/library/src/containers/Sidebar/Sidebar.tsx#L351
