Small Patches

[mattsul]

For identifying and locating small issues in Machine Data Hub.

@mattsul thanks for making this issue! There is a typo on the main screen: "mangement" should be "management".

[PeterSulcs]

The links to code and issues on https://machinedatahub.ai/getting-started are pointing to the old github group still.

The header bar seems kinda crowded now. I think we could

1. Consider removing Home and just have the Machine Data Hub "logo" accomplish this (it already does)
2. Making Suggest a Dataset an icon or a link on the footer.

[mattsul]

Turned Suggest a Dataset into text. Also added it to the About page. Can change into icon whenever.
