Improve GitHub profile

[saragerion]

Suggestion/Improvement

Description

Improve our GitHub profile:
https://github.com/shesharpnl/.github/blob/main/profile/README.md

Right now we have something in place, but I think it can be improved in terms of useful information, and actionable items (and also esthetically).

Motivation

Benefits include (but are not limited to):

• The GitHub profile can be used to highlight projects and initiatives that SheSharp is working on.
• A well-maintained GitHub profile facilitates and encourages community engagement.

Implementation (if applicable)

Examples:
https://github.com/github/.github/blob/main/profile/README.md
https://github.com/grafana/.github/blob/main/profile/README.md
https://github.com/cncf/.github/blob/master/profile/README.md

Do we have a SheSharp banner, @saragerion?

We do not, but I will leave the opportunity to the community to create one and unleash their creativity (if they wish so) :D

Here are the logo files:
