Create landing page for "History"

[chkw-rks]

Created the issue to backup the current text about the history for a future implementation into a dedicated landing page.

Xenko was originally started by Silicon Studio, a technology and services company of 300+ employees founded in 2000, dedicated to driving entertainment forward. Silicon Studio develops world-class products to help developers maximize the potential of leading-edge digital media technology.

In 2018, Xenko was transformed by Silicon Studio into an independent project, driven by an open-source community.
In 2020, the project formerly known as Xenko took on a new identity as Stride.
Then, in May of 2021, Stride proudly became a member of the .NET Foundation.
